One 186 KB HTML file, no libraries: Claude writes a naked-eye 3D aquarium film

A Reddit user had Claude Code build a 186 KB, 3,000-line single HTML file in raw WebGL — no libraries, no textures — rendering a glasses-free 3D aquarium with 960 fish, whale shark, jellyfish and 335 glass shards, all generated mathematically at load time. Opus subagents handled four set pieces; rendering used headless Chromium with 64-sample averaging per frame for real depth-of-field and motion blur (3,900 frames at 1080p60 in 22 minutes).
