Single HTML File Runs Advanced Ocean Simulation: Opus 5.5 and Claude Code Deliver 61 KB Visual Physics Engine

A complete, physically accurate ocean renderer now fits in a 61 KB HTML file—built by Claude Code and Opus 5.5 in under an hour, using iterative AI feedback to refine visual quality. The web-ocean project demonstrates how modern foundation models can generate complex, self-contained interactive applications. The renderer produces real-time ocean dynamics including Tessendorf FFT wave simulation across six cascades of 256×256 samples, whitecaps, sun glitter, and a physically-based sunset sky with self-shadowing clouds. The entire application—vertices, shaders, textures, and UI—compiles into a single deployable file that runs directly in Chrome from a local file system with no external dependencies.
