Show HN: 500 clocks in one 6.3 MB HTML file by Opus 5.5

A user tested frontier models by having them create self-contained web pages displaying clocks, a personal metric inspired by Simon Willison. The user was particularly impressed by the variety, interest, and quality of 500 clocks created by Claude Opus 5.5 over several sessions in its chat interface. These clocks are contained within a single 6.3 MB HTML file.
