Five Hundred Clocks
A gallery of 500 working clocks, each telling the time a different way
It is a concrete, browsable measure of how much range one frontier model has when asked for the same small thing again and again.
Tom Gally directed Claude Opus 5.5 to build 500 animated clocks, from number systems and historical instruments to games, crafts, cellular automata and mathematical constructions. They all live in a single offline HTML page with no libraries or network calls. A toolbar filters by category, searches, pauses, speeds time up to 3600x and shifts it twelve hours either way, and each clock opens with notes on how to read it. The code and text are released under CC0. Gally says the build used roughly 15 million tokens, and some commenters found many clocks weak or barely about time.
