A Reddit user showed off an ocean simulation that Claude Opus 5.5 wrote in 30 minutes as a single 61KB HTML file. The screenshot shows a steady 90fps (11.81ms GPU frame time) at 2560x1440 with 859 nodes, plus mouse look, WASD movement, and interactive panels. It needs a reasonably good GPU to run smoothly; the file is publicly available to try. Another striking data point for frontier coding models' one-shot generation ability.
