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

Lately I've been testing frontier models by having them create self-contained web pages that display clocks--sort of my personal version of Simon Willison’s pelican-on-a-bicycle metric.

I have been particularly impressed by the variety, interest, and quality of the clocks created by Claude Opus 5.5. Over the course of several sessions in the Claude chat interface, I had it build a total of 500 clocks.

Claude’s summary of the prompting process and page design is here:
