A developer asked Claude to "build me a summer festival" — it wrote 24,000 lines of code in one day, producing a walkable anime-style seaside town rendered with Three.js on WebGPU:
- Playable mini-games: goldfish scooping, takoyaki, ring toss, and fireworks over the sea
- Open-sourced at GitHub (StarKnightt/summer-festival) with a PROMPTS.md documenting the generation process
- Stack: TypeScript, Vite, Blender/Mixamo assets, cel-shading, Web Audio
The author shared the prompt, code, and a hosted playable link.
