Generate an SVG of a pelican riding a bicycle.

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.

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.

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.
