Build "Gummy Bears" - a single self-contained HTML file (three.js from a CDN is the only dependency): a handful of translucent gummy bears on a white table that you can grab, stretch, squash, throw and pour. The bears - Classic gummy bear silhouette: round head with two ears, short snout, plump body, stubby arms and legs, tiny molded eyes and nose - Every part melts smoothly into the next - build the body as an implicit surface (metaballs / marching cubes), not separate spheres - Material: real gummy candy. Translucent with transmission and refraction, colored light absorption that gets deeper in thick parts, glossy clearcoat with sharp highlights - Colors: cherry red, orange, lemon yellow, apple green, clear pineapple - Soft colored shadow under each bear, tinted by the bear's own color Physics (this is the whole point - it must feel like jelly, not plastic) - Each bear is a soft body: mass points for head, ears, snout, body, belly, hands and feet, held together by volume-preserving shape matching - Limbs and neck are rendered as stretchy strands between points, getting thinner as they stretch - Grab any part and pull: it stretches like rubber, the rest of the bear leans after it, on release it snaps back with a damped wobble - Pull the head up: the neck stretches, the body follows, on release the bear squashes and hops - Press down on the head: the bear pancakes, bulges sideways, then launches itself back up - Throw a bear: it flies, squashes on landing, bounces and pushes other bears out of the way - Bears collide with each other and never pass through one another - Idle bears do small random hops with squash and stretch - "Pour more bears" drops a handful from above into a wobbling, jiggling pile UI - Editorial product-page style on a white background. Large italic serif title "Gummy / Bears.", a short subtitle, a minimal card on the right with flavor swatches, a wobble slider, live "Stretch" and "Bounces" readouts and a "Pour more bears" button - A subtle circular cursor that grows while grabbing - ACES tone mapping, environment reflections, soft key and back light. Smooth 60fps

build a cinematic 3D animation that explains how a Tesla-style electric motor works
I had Claude Code (Opus 5.5) create a 3D diagram of a piston and crank moving in Three.js overnight from a one-line request. The work took 8 minutes. ■ What was created - Piston, connecting rod, crank (main shaft, arm, pin, flywheel), transparent cylinder, head, spark plug, flame in the combustion chamber - A vertical 1080x1920 @ 30fps video, 32 seconds long, using Remotion - No image assets were used at all. Parts and flames are all drawn with code. ■ How it works - The height of the piston and the angle of the connecting rod are calculated every frame using formulas based on the crank's angle. - Since it's a 4-stroke engine, the combustion chamber lights up only once every 720°, right after top dead center. - The lines for part labels are drawn by projecting 3D points onto the screen using the same camera. So even if you rotate or zoom around, the lines correctly point to the parts. ■ How to make it (3 steps) 1. The request was just one line: "Make a rotatable and zoomable 3D diagram of piston and crank movement in Three.js" 2. Assemble it using only the pre-installed @remotion/three and @react-three/fiber. No additional installations. 3. Check intermediate still images 3 times, fix the orientation of the piston rings, camera distance and height, and overlapping of labels and graphs before exporting. Even with headless rendering (--gl=angle), the 3D model comes out as is, and the export finished in one go. ■ Notes - I didn't install or try the 'Anatomy' skill from the original post. I just assembled it with my local Three.js setup. - The flame is made of semi-transparent glowing cylinders and point lights. I didn't do WebGL shader-based fire, water, or plasma like the original post. - The counterweights on the crank have simplified shapes, so depending on the angle, some frames may look like dark boards. - Viewers cannot rotate or zoom themselves. The camera moves within the video to show different angles.

Build a live trait scanner interface for a Pudgy Penguin NFT. Subject: One specific Pudgy Penguin image. Pipeline: Hair -> Eyes -> Medal -> Full Scan -> Grade. Steps: 1. Lock one subject and one pipeline: hair, eyes, medal, full scan, then the grade. 2. Write the trait dictionary first so the model never invents parts that are not on the body. 3. Build the center stage: the penguin, the aim reticle, the FULL SCAN badge. 4. Add the left read as traits only: afro, pick, eyes, beak, fur, medal, ribbon, aura. 5. Add the right read as scan stats only: conf, depth, rate, lock, sway. 6. Wire the lower deck last: star path, crystal ball, rune track, mana curve. 7. Play the scan end to end and fix one panel at a time until the lock feels real. Rules: - One step owns one read. - The verdict never runs before the full silhouette is locked. Start with one penguin, then the next scan is just a new subject in the same machine.

I had Claude Code (Opus 5.5) create a 3D diagram of a piston and crank moving in Three.js overnight from a one-line request. The work took 8 minutes. ■ What was created - Piston, connecting rod, crank (main shaft, arm, pin, flywheel), transparent cylinder, head, spark plug, flame in the combustion chamber - A vertical 1080x1920 @ 30fps video, 32 seconds long, using Remotion - No image assets were used at all. Parts and flames are all drawn with code. ■ How it works - The height of the piston and the angle of the connecting rod are calculated every frame using formulas based on the crank's angle. - Since it's a 4-stroke engine, the combustion chamber lights up only once every 720°, right after top dead center. - The lines for part labels are drawn by projecting 3D points onto the screen using the same camera. So even if you rotate or zoom around, the lines correctly point to the parts. ■ How to make it (3 steps) 1. The request was just one line: "Make a rotatable and zoomable 3D diagram of piston and crank movement in Three.js" 2. Assemble it using only the pre-installed @remotion/three and @react-three/fiber. No additional installations. 3. Check intermediate still images 3 times, fix the orientation of the piston rings, camera distance and height, and overlapping of labels and graphs before exporting. Even with headless rendering (--gl=angle), the 3D model comes out as is, and the export finished in one go. ■ Notes - I didn't install or try the 'Anatomy' skill from the original post. I just assembled it with my local Three.js setup. - The flame is made of semi-transparent glowing cylinders and point lights. I didn't do WebGL shader-based fire, water, or plasma like the original post. - The counterweights on the crank have simplified shapes, so depending on the angle, some frames may look like dark boards. - Viewers cannot rotate or zoom themselves. The camera moves within the video to show different angles.
