Claude Code reportedly built a browser-based Avatar-style waterbending sim in 9 hours

Vjeux · x · 2026-07-29

A vibe-coded Avatar-style waterbending simulator runs entirely in the browser, with real fluid physics, surfable waves, snowfall, dynamic lighting, procedural terrain, cloth simulation, and persistent snow deformation.

According to the post, the creator spent about 9 hours and 4 million tokens building it. Claude Code with Opus 5 reportedly handled the project end to end: planning the architecture, writing the WebGPU and Babylon.js systems, profiling performance, and iterating from screenshots of its own output.
