Developer Builds Photorealistic Ocean in Single HTML File Using Claude Opus 5.5

A developer has created a real-time WebGPU ocean renderer as a self-contained 61 KB HTML file using Claude Code and Opus 5.5, showcasing the model's capacity for graphics programming and complex algorithmic rendering. The project, named web-ocean, features FFT-based wave simulation across six cascades of 256×256 samples, physically-based sky rendering with volumetric cloud layers, sun glitter effects, and a free-flying camera—all implemented from scratch without graphics engines or rendering libraries.
