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

Original Summary

Lately I&#x27;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.<p>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.<p>Claude’s summary of the prompting process and page design is here:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;tkgally&#x2F;500-clocks&#x2F;tree&#x2F;main" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tkgally&#x2F;500-clocks&#x2F;tree&#x2F;main</a>
