A browser ocean in one 61 KB HTML file: WebGPU FFT waves, whitecaps, sun glitter and a physically based sunset sky with clouds, built with Claude Code and Claude Opus 5.5 in about 30 minutes, per its creator.
One model’s result, not a side-by-side. See other models on Ocean / wave simulation; prompts, tools and time differ, so compare loosely.
