Tkgally

Tkgally is a single self-contained HTML page displaying 500 clocks, all generated by Claude Opus 5.5. It is part of the author's informal method for testing frontier models by asking them to build self-contained web pages that display clocks, a personal counterpart to Simon Willison's pelican-on-a-bicycle test.

The clocks were built over several sessions in the Claude chat interface. The author highlights the variety, interest, and quality of the results. A linked summary from Claude describes the prompting process and page design.
