Round 1: a pelican riding a bicycle
All ten are SVGs, so they stay sharp at any size.
Generate an SVG of a pelican riding a bicycle.
Round 2: 20 balls in a spinning heptagon
This is Qwen 3.8 Max's. Open the others with the buttons.
ExperimentThe Heptagon Bouncing Balls TestOpen →Write a single HTML file (HTML, CSS and JavaScript, no external libraries) that shows 20 numbered balls bouncing inside a spinning heptagon. The heptagon rotates slowly around its center. The balls fall under gravity, bounce off the heptagon's walls realistically (the walls are moving because of the rotation, and there is some friction), collide with each other, and must never escape the heptagon. Each ball shows its number, and the number visibly rotates as the ball spins. Output only the complete HTML file.
Mia's tips
- Qwen thinks for a long time on every task. This one took about 15 minutes, so be patient.
Round 3: Tetris
Qwen 3.8 Max's version: click the picture to open it on its own page, where the game fills the whole window: arrow keys move and rotate, space drops. You'll need a keyboard.
▶ Play it on its own page
Make a complete, playable Tetris game in a single HTML file (no external libraries). Arrow keys move and rotate the piece, space does a hard drop. Include a ghost piece, a next-piece preview, line clearing with score and levels, and a game-over screen with restart. Output only the complete HTML file.
Mia's tips
- Gemini's restart is a "Play Again" button; the keyboard won't do it.
The final: a 3D lighthouse island
Claude Opus 5.5's island. One day-night cycle every 30 seconds; wait for night and the lighthouse.
3DLighthouse IslandOpen →Build a single HTML file that uses Three.js (load it from a CDN) to render a small low-poly island in the ocean: a lighthouse with a rotating light beam, a few palm trees, animated waves, and a full day-night cycle every 30 seconds, with stars at night. The camera slowly orbits the island. Output only the complete HTML file.
Mia's tips
- I ran Claude and GPT in their own coding tools (Claude Code, and Codex with GPT on max reasoning), and the other six straight through their APIs on default settings. Each task ran once.
