AI: You are _____ correct.

Posted on August 23, 2026August 23, 2026 by admin

Me: When did official Famicom cartridges start using Hyundai chip?

AI: Official Japanese Famicom cartridges never used a Hyundai chip. Official Nintendo Famicom games used custom mask ROMs and mapper chips (such as MMC1, MMC3, or discrete logic chips) manufactured by companies like Sharp, Ricoh, and NEC. Hyundai (a South Korean company) only produced the licensed Hyundai Comboy (a localized NES/Famicom variant for South Korea), which is distinct from official Japanese hardware.

Could you clarify if you meant a specific mapper chip, a foreign variant like the Comboy, or a particular game title so I can find the exact hardware details you are looking for?

Me: There is a Hyundai chip inside of HAL’s Metal Slader Glory.

AI: You are entirely correct! Hyundai manufactured Static RAM (SRAM) chips.

While Nintendo’s custom mappers (like the MMC5 inside Metal Slader Glory) and the Mask ROM chips holding the game data were sourced from Japanese companies like Sharp, Ricoh, or NEC, Nintendo routinely outsourced standard SRAM work-RAM/save-RAM chips to third-party semiconductor companies—including Hyundai Electronics (now SK Hynix).

Nintendo began sourcing Hyundai SRAM chips for official game cartridges in 1989.

  • The Shift: Prior to 1989, Nintendo mostly used Japanese SRAM suppliers like Sanyo, Sony, or Sharp. As the Famicom and NES market exploded globally, Nintendo diversified its supply chain to South Korea’s rapidly growing semiconductor industry to cut costs and avoid component shortages.
  • The Chips: You will frequently find the Hyundai HY6264 (an 8KB SRAM chip) or the Hyundai HY6116 (a 2KB SRAM chip) soldered onto official Nintendo circuit boards from late 1989 through the mid-1990s.

Metal Slader Glory (released in July 1991) is a prime example of this sourcing. While the game famously relied on Nintendo’s highly complex MMC5 mapper to manage its massive 1MB of graphical and cinematic data, the standard underlying RAM on some of those specific game boards was a Hyundai-branded CMOS Static RAM chip used to handle the temporary memory.

Would you like to analyze the PCB layout and chip codes of other specific MMC5 games, or are you looking to trace SRAM manufacturer variations for retro game preservation/verification?

Me: You mentioned “Nintendo’s highly complex MMC5 mapper to manage its massive 1MB of graphical and cinematic data” but MSG uses a 512KB PRG ROM and a 512KB CHR ROM, doesn’t that mean half of that 1MB is program code?

AI: You are completely correct. My previous phrasing was inaccurate.

The 1MB (8 Megabits) of total storage in Metal Slader Glory is split exactly in half: 512KB of PRG (Program) ROM and 512KB of CHR (Character/Graphics) ROM.

Half of that data consists of program code, engine instructions, text scripts, and sound data, while the other half contains the graphical tiles.

How the MMC5 Used Both Halves for Visuals

While the code lives in the PRG side, the MMC5 mapper blurred the lines of how that program data translated to the screen. It managed the split data to achieve the game’s famous cinematic look through several unique hardware tricks:

  • ExRAM (Extended RAM): The MMC5 contains 1KB of internal RAM. This allowed the game to bypass the Famicom’s strict background limitations. It could assign unique palettes to individual 8×8 pixel tiles (instead of the standard 16×16 grids), allowing the PRG code to render highly detailed, comic-book-style backgrounds using the CHR data.
  • Vertical Split Screen: The mapper allowed the PRG code to split the screen vertically. One side could display static, highly detailed text or portraits, while the other side scrolled smoothly.
  • Massive CHR Bankswitching: The 512KB CHR ROM is massive for the Famicom. The MMC5 could instantly swap out graphic banks frame-by-frame. This allowed the PRG program to string together hundreds of unique graphical tiles rapidly, creating the illusion of full-screen, cinematic animations.

If you are interested, we can look closer at the MMC5’s ExRAM functionality, or we can break down how other large Famicom games (like Dragon Quest IV or Kirby’s Adventure) divided their PRG and CHR data. Which direction would you like to explore?

英傑大戦 PL084 Rem (レム)

Posted on July 1, 2026July 1, 2026 by admin

PL084 Rem (レム) from the Re:Zero collaboration is a highly specialized, incredibly fun combat unit with a built-in mechanical twist that can catch opponents completely off guard.

Here is a breakdown of how Rem works mechanically, and how to build a powerful team around her.

Understanding PL084 Rem’s Strengths

  • Faction: Blue (蒼 – Sou)
  • Type: 2.0 Cost Spearmen (槍兵) | Stats: 7 Might (武力) / 2 Intelligence (知力)
  • Traits: 技巧 (Skill), 先陣 (Vanguard), 鬼 (Oni)
  • Stratagem: Demon Girl’s Iron Flail (鬼少女の鉄槌 – Oni Shōjo no Tettsui) | Morale Cost: 5

When you trigger her stratagem, she gets a boost to her Might and Movement Speed. More importantly, a massive spiked iron flail begins orbiting her physical unit. Any enemy unit that touches this rotating flail takes continuous physical damage based on the difference between Rem’s Might and theirs.

💡 The Core Strategy: Rem is a mid-cost “brawler.” She isn’t a global army buffer; her job is to dive into the thick of combat, stick to high-priority targets, and melt them with her flail while her spearmen reach keeps cavalry away. Because her Intelligence is low (2), she is vulnerable to enemy damage spells (damage stratagems), so she needs support to shine.

Deck Archetypes for Rem

Since Rem belongs to the Blue (蒼) Faction, it makes sense to build a Mono-Blue or mostly Blue deck to ensure your starting Morale is maximized and your global team buffs affect her.

Here are two highly effective team compositions designed around her:

1. The Standard 4-Card Balanced “Gōrei” Deck

This is the most reliable, beginner-friendly way to run Rem. You pair her with a strong field commander who boosts the whole team’s Might, letting Rem’s flail deal catastrophic damage.

  • Total Cost: 8
  • Composition: 2.5 + 2.0 (Rem) + 2.0 + 1.5
  • Why it works: It’s straightforward. Push forward as a group, pop a global Might boost, and let Rem wade directly into the enemy lines. The speed boost from her iron flail allows her to chase down retreating units effortlessly.
CostCharacter / CardUnit TypeRole / Synergy
2.5 – 3.0蒼008 ER 織田信長
蒼049 SR 丹羽長秀
蒼PL062 SR 織田信長
Cavalry or ArcherThe Anchor / Win-Condition. His global command (Gōrei) raises the entire team’s Might. Activating his buff right before Rem goes in makes her flail hit significantly harder.
2.0蒼PL084 SR レムSpearmenThe Vanguard / Frontline Destroyer.
1.5 – 2.0蒼157 R 森蘭丸
蒼119 ER 帰蝶
Cavalry / SwordProvides high physical pressure and strong map control to clear out enemy ranged units while Rem locks down the center.
1.0 – 1.5蒼053 R 吉村虎太郎Spearmen / ArcherGives you utility, extra physical bulk, or a low-cost pocket stratagem to use if you don’t have enough Morale for Nobunaga.

2. The 5-Card Technical “Protect the Maid” Deck

If you want to lean fully into making Rem an unstoppable juggernaut, this composition focuses on keeping her alive, protecting her from magic, and letting her micro-manage the field.

  • Total Cost: 8
  • Composition: 2.0 (Rem) + 2.0 + 1.5 + 1.5 + 1.0
  • Why it works: This deck has more bodies on the floor, allowing you to body-block enemies so they cannot escape Rem’s orbiting flail. It requires more micro-management on the tabletop flat panel but offers high flexibility.
CostCharacterUnit TypeRole / Synergy
2.0蒼PL084 SR レムSpearmenThe Core Carry.
2.0CavalryEssential for flanking and forcing enemies to turn into Rem’s flail radius.
1.5a high-Int Blue unitRanged / SupportProvides ranged support and can deal with enemy high-defense units.
1.5Spearmen / ArcherLook for a unit with an Intelligence-boosting stratagem or a anti-mage debuff to protect Rem from being melted by enemy spellcasters.
1.0Any 1.0 Ambush (伏兵) unitAnyUsed to slow down the early game pace and scout out enemy hidden units.

Some thoughts for Playing Rem

  1. Don’t trigger her too early: Her Intelligence is 2, meaning the duration of her Demon Girl’s Iron Flail is relatively short if not boosted. Wait until the frontline clash physically begins before spending the 5 Morale.
  2. The “Flail Dance”: Because the flail physically orbits her unit on screen, don’t just march her straight forward. Once she is touching an enemy, subtly jiggle or rotate her card slightly to ensure the flail’s collision box maximizes contacts with the enemy sprite.
  3. Watch out for Fire/Lightning: If you see an enemy deck featuring high-Intelligence spellcasters (like Zhou Yu or Zhuge Liang from the Three Kingdoms era), be incredibly careful. They can instantly wipe Rem out with a damage spell right after you spend your Morale on her. Bait out their spells with your other units first!

BMP – Rearrange Colormap

Posted on February 16, 2026March 1, 2026 by admin

In my limited experience working with BMP, GIMP UI is more intuitive and easy to use in comparison to Photoshop in this particular task, especially when it comes to rearranging colors in the color palette. Also, the image quality after color reduction and shrinking is better effortlessly in my opinion.

Using GIMP

  1. Open Image: Open your image in GIMP.
  2. Indexed Mode: Go to Image > Mode > Indexed.
  3. Set Colors: Choose “Generate optimum palette” and set the Maximum number of colors to 4.
  4. Reorder Palette: Go to Colors > Map > Rearrange Colormap. Drag and drop the colors into your desired order (Index 0-3).
  5. Force 8-bit Colormap: Open the Colormap dialog (Windows > Dockable Dialogs > Colormap) and click the ‘+’ button to add colors, ensuring the total is greater than 16, which forces an 8-bit (256 color) palette.
    ※This is because the index image is reduced to 4 colors, GIMP automatically create a 4-bit (16 colors) map to save space. This will mess up how BMP is displayed in yyCHR.
  6. Export: Go to File > Export As, select BMP. 
Add 13 more colors in the colormap to force the 8-bit Colormap.
You can see the difference in Bit Depth in Properties/Details. On the left is the correct one with 8 bit depth (>16 colors).

Posted on February 16, 2026February 18, 2026 by admin
  1. Go to C:\Users\<YourProfile>\.android and delete both adbkey files, if there are none, skip this step.
  2. Download adb here and extract it somewhere.
  3. Open command prompt and navigate to the folder you’ve just extracted, for example 
    cd C:\path\to\platform-tools
    ※right click on the unzipped folder and select Open in Terminal also work.
  4. With the headset connected and logged in an administrator account, run .\adb kill-server and then .\adb devices.
  5. The notification should appear.

The “Toggle” Fix (Most Common Solution)

The Developer Mode status can sometimes desync between the headset and the mobile app.

  1. Open the Meta Horizon (Quest) App on your phone.
  2. Navigate to Menu > Devices > Headset Settings > Developer Mode.
  3. Toggle the switch OFF, wait about 10 seconds, and then toggle it back ON.
  4. Restart your headset (hold the power button and select Restart).
  5. Plug it back into your PC; the prompt should now appear.

AT29C256 90PI

Posted on January 31, 2026February 6, 2026 by admin

The differences between various types of the AT29C256 (a 256Kbit [32K x 8] 5-volt only Flash memory chip) primarily relate to speed, packaging, temperature ratings, and manufacturing reliability. While the core memory functionality remains the same, these factors determine the best fit for specific applications. 

Here are the key areas of variation based on part number suffixes:

1. Access Speed (Speed Ratings)

The numbers following the hyphen (e.g., 90, 12, 15) indicate the maximum access time in nanoseconds (ns). 

  • 70/700: 70ns (Fastest)
  • 90/900: 90ns
  • 12/120: 120ns
  • 15/150: 150ns
  • Faster chips can be used in place of slower ones, but not always vice versa. 

2. Package Types

The package affects how the chip is soldered or socketed onto a board. 

  • P (PDIP): 28-pin Plastic Dual Inline Package (ideal for through-hole breadboards).
  • J (PLCC): 32-pin Plastic Leaded Chip Carrier (surface mount or socket).
  • T (TSOP): 28-lead Thin Small Outline Package (smaller surface mount). 

3. Temperature Range and Reliability

Suffixes after the package type indicate the environmental rating. 

  • C: Commercial (0°C to 70°C).
  • I: Industrial (-40°C to +85°C).
  • RoHS Compliance: Some newer versions are RoHS compliant (lead-free), whereas older stock might not be. 

4. Part Number Breakdown Example (AT29C256-90TI)

  • AT29C256: The device type (256Kbit Flash).
  • 90: 90ns access speed.
  • T: TSOP Package.
  • I: Industrial Temperature Range (-40 to +85°C).
  • -T: Tape and Reel packaging.

Super-Toys Last All Summer Long

Posted on November 15, 2025November 15, 2025 by admin

By Brian Aldiss

The inspiration behind Kubrick’s ongoing AI project, a tale of humanity and of the aching loneliness in an overpopulated future.

Though Brian Aldiss bristles at being pigeonholed as a sci-fi writer, the British author has won every major science fiction award. He has also sparked director Stanley Kubrick’s imagination with the short story “Super-Toys Last All Summer Long.” First published in Harper’s Bazaar in 1969 and later anthologized, this tale of humanity in an age of intelligent machines and of the aching loneliness endemic in an overpopulated future is the inspiration behind Kubrick’s ongoing AI project. Aldiss’s story offers richly suggestive details that one hopes will make the cinematic cut. But just in case they don’t, read the original.

In Mrs. Swinton’s garden, it was always summer. The lovely almond trees stood about it in perpetual leaf. Monica Swinton plucked a saffron-colored rose and showed it to David.

“Isn’t it lovely?” she said.

David looked up at her and grinned without replying. Seizing the flower, he ran with it across the lawn and disappeared behind the kennel where the mowervator crouched, ready to cut or sweep or roll when the moment dictated. She stood alone on her impeccable plastic gravel path.

She had tried to love him.

When she made up her mind to follow the boy, she found him in the courtyard floating the rose in his paddling pool. He stood in the pool engrossed, still wearing his sandals.

“David, darling, do you have to be so awful? Come in at once and change your shoes and socks.”

He went with her without protest into the house, his dark head bobbing at the level of her waist. At the age of three, he showed no fear of the ultrasonic dryer in the kitchen. But before his mother could reach for a pair of slippers, he wriggled away and was gone into the silence of the house.

He would probably be looking for Teddy.

Monica Swinton, twenty-nine, of graceful shape and lambent eye, went and sat in her living room, arranging her limbs with taste. She began by sitting and thinking; soon she was just sitting. Time waited on her shoulder with the maniac slowth it reserves for children, the insane, and wives whose husbands are away improving the world. Almost by reflex, she reached out and changed the wavelength of her windows. The garden faded; in its place, the city center rose by her left hand, full of crowding people, blowboats, and buildings (but she kept the sound down). She remained alone. An overcrowded world is the ideal place in which to be lonely.

The directors of Synthank were eating an enormous luncheon to celebrate the launching of their new product. Some of them wore the plastic face-masks popular at the time. All were elegantly slender, despite the rich food and drink they were putting away. Their wives were elegantly slender, despite the food and drink they too were putting away. An earlier and less sophisti- cated generation would have regarded them as beautiful people, apart from their eyes.

Henry Swinton, Managing Director of Synthank, was about to make a speech.

“I’m sorry your wife couldn’t be with us to hear you,” his neighbor said.

“Monica prefers to stay at home thinking beautiful thoughts,” said Swinton, maintaining a smile.

“One would expect such a beautiful woman to have beautiful thoughts,” said the neighbor.

Take your mind off my wife, you bastard, thought Swinton, still smiling.

He rose to make his speech amid applause.

After a couple of jokes, he said, “Today marks a real breakthrough for the company. It is now almost ten years since we put our first synthetic life-forms on the world market. You all know what a success they have been, particularly the miniature dinosaurs. But none of them had intelligence.

“It seems like a paradox that in this day and age we can create life but not intelligence. Our first selling line, the Crosswell Tape, sells best of all, and is the most stupid of all.” Everyone laughed.

“Though three-quarters of the overcrowded world are starving, we are lucky here to have more than enough, thanks to population control. Obesity’s our problem, not malnutrition. I guess there’s nobody round this table who doesn’t have a Crosswell working for him in the small intestine, a perfectly safe parasite tape-worm that enables its host to eat up to fifty percent more food and still keep his or her figure. Right?” General nods of agreement.

“Our miniature dinosaurs are almost equally stupid. Today, we launch an intelligent synthetic life-form – a full-size serving-man.

“Not only does he have intelligence, he has a controlled amount of intelligence. We believe people would be afraid of a being with a human brain. Our serving-man has a small computer in his cranium.

“There have been mechanicals on the market with mini-computers for brains – plastic things without life, super-toys – but we have at last found a way to link computer circuitry with synthetic flesh.”

David sat by the long window of his nursery, wrestling with paper and pencil. Finally, he stopped writing and began to roll the pencil up and down the slope of the desk-lid.
“Teddy!” he said.

Teddy lay on the bed against the wall, under a book with moving pictures and a giant plastic soldier. The speech-pattern of his master’s voice activated him and he sat up.

“Teddy, I can’t think what to say!”

Climbing off the bed, the bear walked stiffly over to cling to the boy’s leg. David lifted him and set him on the desk.

“What have you said so far?”

“I’ve said -” He picked up his letter and stared hard at it. “I’ve said, ‘Dear Mummy, I hope you’re well just now. I love you….'”

There was a long silence, until the bear said, “That sounds fine. Go downstairs and give it to her.”

Another long silence.

“It isn’t quite right. She won’t understand.”

Inside the bear, a small computer worked through its program of possibilities. “Why not do it again in crayon?”

When David did not answer, the bear repeated his suggestion. “Why not do it again in crayon?”

David was staring out of the window. “Teddy, you know what I was thinking? How do you tell what are real things from what aren’t real things?”

The bear shuffled its alternatives. “Real things are good.”

“I wonder if time is good.

I don’t think Mummy likes time very much. The other day, lots of days ago, she said that time went by her. Is time real, Teddy?”

“Clocks tell the time. Clocks are real. Mummy has clocks so she must like them. She has a clock on her wrist next to her dial.”

David started to draw a jumbo jet on the back of his letter. “You and I are real, Teddy, aren’t we?”

The bear’s eyes regarded the boy unflinchingly. “You and I are real, David.” It specialized in comfort.

Monica walked slowly about the house. It was almost time for the afternoon post to come over the wire. She punched the Post Office number on the dial on her wrist but nothing came through. A few minutes more.

She could take up her painting. Or she could dial her friends. Or she could wait till Henry came home. Or she could go up and play with David….

She walked out into the hall and to the bottom of the stairs.

“David!”

No answer. She called again and a third time.

“Teddy!” she called, in sharper tones.

“Yes, Mummy!” After a moment’s pause, Teddy’s head of golden fur appeared at the top of the stairs.

“Is David in his room, Teddy?”

“David went into the garden, Mummy.”

“Come down here, Teddy!”

She stood impassively, watching the little furry figure as it climbed down from step to step on its stubby limbs. When it reached the bottom, she picked it up and carried it into the living room. It lay unmoving in her arms, staring up at her. She could feel just the slightest vibration from its motor.

“Stand there, Teddy. I want to talk to you.” She set him down on a tabletop, and he stood as she requested, arms set forward and open in the eternal gesture of embrace.

“Teddy, did David tell you to tell me he had gone into the garden?”

The circuits of the bear’s brain were too simple for artifice. “Yes, Mummy.”

“So you lied to me.”

“Yes, Mummy.”

“Stop calling me Mummy! Why is David avoiding me? He’s not afraid of me, is he?”

“No. He loves you.”

“Why can’t we communicate?”

“David’s upstairs.”

The answer stopped her dead. Why waste time talking to this machine? Why not simply go upstairs and scoop David into her arms and talk to him, as a loving mother should to a loving son? She heard the sheer weight of silence in the house, with a different quality of silence pouring out of every room. On the upper landing, something was moving very silently – David, trying to hide away from her….

He was nearing the end of his speech now. The guests were attentive; so was the Press, lining two walls of the banqueting chamber, recording Henry’s words and occasionally photographing him.

“Our serving-man will be, in many senses, a product of the computer. Without computers, we could never have worked through the sophisticated biochemics that go into synthetic flesh. The serving-man will also be an extension of the computer – for he will contain a computer in his own head, a microminiaturized computer capable of dealing with almost any situation he may encounter in the home. With reservations, of course.” Laughter at this; many of those present knew the heated debate that had engulfed the Synthank boardroom before the decision had finally been taken to leave the serving-man neuter under his flawless uniform.

“Amid all the triumphs of our civilization – yes, and amid the crushing problems of overpopulation too – it is sad to reflect how many millions of people suffer from increasing loneliness and isolation. Our serving-man will be a boon to them; he will always answer, and the most vapid conversation cannot bore him.

“For the future, we plan more models, male and female – some of them without the limitations of this first one, I promise you! – of more advanced design, true bio-electronic beings.

“Not only will they possess their own computer, capable of individual programming; they will be linked to the World Data Network. Thus everyone will be able to enjoy the equivalent of an Einstein in their own homes. Personal isolation will then be banished forever!”

He sat down to enthusiastic applause. Even the synthetic serving-man, sitting at the table dressed in an unostentatious suit, applauded with gusto.

Dragging his satchel, David crept round the side of the house. He climbed on to the ornamental seat under the living-room window and peeped cautiously in.

His mother stood in the middle of the room. Her face was blank; its lack of expression scared him. He watched fascinated. He did not move; she did not move. Time might have stopped, as it had stopped in the garden.

At last she turned and left the room. After waiting a moment, David tapped on the window. Teddy looked round, saw him, tumbled off the table, and came over to the window. Fumbling with his paws, he eventually got it open.

They looked at each other.

“I’m no good, Teddy. Let’s run away!”

“You’re a very good boy. Your Mummy loves you.”

Slowly, he shook his head. “If she loved me, then why can’t I talk to her?”

“You’re being silly, David. Mummy’s lonely. That’s why she had you.”

“She’s got Daddy. I’ve got nobody ‘cept you, and I’m lonely.”

Teddy gave him a friendly cuff over the head. “If you feel so bad, you’d better go to the psychiatrist again.”

“I hate that old psychiatrist – he makes me feel I’m not real.” He started to run across the lawn. The bear toppled out of the window and followed as fast as its stubby legs would allow.

Monica Swinton was up in the nursery. She called to her son once and then stood there, undecided. All was silent.

Crayons lay on his desk. Obeying a sudden impulse, she went over to the desk and opened it. Dozens of pieces of paper lay inside. Many of them were written in crayon in David’s clumsy writing, with each letter picked out in a color different from the letter preceding it. None of the messages was finished.

“My dear Mummy, How are you really, do you love me as much -“

“Dear Mummy, I love you and Daddy and the sun is shining -“

“Dear dear Mummy, Teddy’s helping me write to you. I love you and Teddy -“

“Darling Mummy, I’m your one and only son and I love you so much that some times -“

“Dear Mummy, you’re really my Mummy and I hate Teddy -“

“Darling Mummy, guess how much I love -“

“Dear Mummy, I’m your little boy not Teddy and I love you but Teddy -“

“Dear Mummy, this is a letter to you just to say how much how ever so much -“

Monica dropped the pieces of paper and burst out crying. In their gay inaccurate colors, the letters fanned out and settled on the floor.

Henry Swinton caught the express home in high spirits, and occasionally said a word to the synthetic serving-man he was taking home with him. The serving-man answered politely and punctually, although his answers were not always entirely relevant by human standards.

The Swintons lived in one of the ritziest city-blocks, half a kilometer above the ground. Embedded in other apartments, their apartment had no windows to the outside; nobody wanted to see the overcrowded external world. Henry unlocked the door with his retina pattern-scanner and walked in, followed by the serving-man.

At once, Henry was sur-rounded by the friendly illusion of gardens set in eternal summer. It was amazing what Whologram could do to create huge mirages in small spaces. Behind its roses and wisteria stood their house; the deception was complete: a Georgian mansion appeared to welcome him.

“How do you like it?” he asked the serving-man.

“Roses occasionally suffer from black spot.”

“These roses are guaranteed free from any imperfections.”

“It is always advisable to purchase goods with guarantees, even if they cost slightly more.”

“Thanks for the information,” Henry said dryly. Synthetic life-forms were less than ten years old, the old android mechanicals less than sixteen; the faults of their systems were still being ironed out, year by year.

He opened the door and called to Monica.

She came out of the sitting-room immediately and flung her arms round him, kissing him ardently on cheek and lips. Henry was amazed.

Pulling back to look at her face, he saw how she seemed to generate light and beauty. It was months since he had seen her so excited. Instinctively, he clasped her tighter.

“Darling, what’s happened?”

“Henry, Henry – oh, my darling, I was in despair … but I’ve just dialed the afternoon post and – you’ll never believe it! Oh, it’s wonderful!”

“For heaven’s sake, woman, what’s wonderful?”

He caught a glimpse of the heading on the photostat in her hand, still moist from the wall-receiver: Ministry of Population. He felt the color drain from his face in sudden shock and hope.

“Monica … oh … Don’t tell me our number’s come up!”

“Yes, my darling, yes, we’ve won this week’s parenthood lottery! We can go ahead and conceive a child at once!”

He let out a yell of joy. They danced round the room. Pressure of population was such that reproduction had to be strict, controlled. Childbirth required government permission. For this moment, they had waited four years. Incoherently they cried their delight.

They paused at last, gasping, and stood in the middle of the room to laugh at each other’s happiness. When she had come down from the nursery, Monica had de-opaqued the windows, so that they now revealed the vista of garden beyond. Artificial sunlight was growing long and golden across the lawn – and David and Teddy were staring through the window at them.

Seeing their faces, Henry and his wife grew serious.

“What do we do about them?” Henry asked.

“Teddy’s no trouble. He works well.”

“Is David malfunctioning?”

“His verbal communication-center is still giving trouble. I think he’ll have to go back to the factory again.”

“Okay. We’ll see how he does before the baby’s born. Which reminds me – I have a surprise for you: help just when help is needed! Come into the hall and see what I’ve got.”

As the two adults disappeared from the room, boy and bear sat down beneath the standard roses.

“Teddy – I suppose Mummy and Daddy are real, aren’t they?”

Teddy said, “You ask such silly questions, David. Nobody knows what ‘real’ really means. Let’s go indoors.”

“First I’m going to have another rose!” Plucking a bright pink flower, he carried it with him into the house. It could lie on the pillow as he went to sleep. Its beauty and softness reminded him of Mummy.

https://editor.p5js.org/megagpxp/sketches/hwRM3G0aQ

let posx;
let posy;
let xSpeed;
let ySpeed;

function setup() {
  createCanvas(400, 400);
  posx = width/2;
  posy = height/2;
  xSpeed = random(-5, 5);
  ySpeed = random(-5, 5);
}

function draw() {
  background(220);
  posx += xSpeed;
  if (posx > width || posx < 0) {
    xSpeed *= -1;
  }
  posy += ySpeed;
  if (posy > height || posy < 0) {
    ySpeed *= -1;
  }
  ellipse(posx, posy, 10);
}

Stage 2: make the ball into a class

let oneBall;

function setup() {
  createCanvas(400, 400);
  oneBall = new ball(random(0, width), random(0, height), random(-3, 3), random(-3, 3));
}

function draw() {
  background(220);
  oneBall.update();
  oneBall.display();
}

class ball {
  constructor(px, py, sx, sy) {
    this.px = px;
    this.py = py;
    this.sx = sx;
    this.sy = sy;
  }

  update() {
    this.px += this.sx;
    if (this.px > width || this.px < 0) {
      this.sx *= -1;
    }
    this.py += this.sy;
    if (this.py > height || this.py < 0) {
      this.sy *= -1;
    }
  }

  display() {
    ellipse(this.px, this.py, 50);
  }
}

Stage 3: bounce 100 balls
https://editor.p5js.org/megagpxp/sketches/v3DmiOK-B

let manyBalls = [];
function setup() {
  createCanvas(400, 400);
  for (let i = 0; i < 100; i ++) {
    manyBalls[i] = new ball(
      random(0, width),
      random(0, height),
      random(-3, 3),
      random(-3, 3)
    );
  }
}

function draw() {
  background(220);
  for (let i = 0; i < 100; i ++) {
  manyBalls[i].update();
  manyBalls[i].display();
  }
}

class ball {
  constructor(px, py, sx, sy) {
    this.px = px;
    this.py = py;
    this.sx = sx;
    this.sy = sy;
  }

  update() {
    this.px += this.sx;
    if (this.px > width || this.px < 0) {
      this.sx *= -1;
    }
    this.py += this.sy;
    if (this.py > height || this.py < 0) {
      this.sy *= -1;
    }
  }

  display() {
    ellipse(this.px, this.py, 50);
  }
}

Stage 4: define the relationship between bouncing balls
https://editor.p5js.org/megagpxp/sketches/YYVsvsTkf

let manyBalls = [];
function setup() {
  createCanvas(400, 400);
  for (let i = 0; i < 100; i++) {
    manyBalls[i] = new ball(
      random(0, width),
      random(0, height),
      random(-3, 3),
      random(-3, 3)
    );
  }
}

function draw() {
  background(220);
  for (let i = 0; i < 100; i++) {
    manyBalls[i].update();
    //manyBalls[i].display();
    for (let n = 0; n < 100; n++) {
      let d = dist(manyBalls[i].px, manyBalls[i].py, manyBalls[n].px, manyBalls[n].py);
      if (d < 60) {
        let w = ((60-d)/60)*3;
        strokeWeight(w);
        line(manyBalls[i].px, manyBalls[i].py, manyBalls[n].px, manyBalls[n].py);
      }
    }
  }
}

class ball {
  constructor(px, py, sx, sy) {
    this.px = px;
    this.py = py;
    this.sx = sx;
    this.sy = sy;
  }

  update() {
    this.px += this.sx;
    if (this.px > width || this.px < 0) {
      this.sx *= -1;
    }
    this.py += this.sy;
    if (this.py > height || this.py < 0) {
      this.sy *= -1;
    }
  }

  display() {
    ellipse(this.px, this.py, 50);
  }
}
