The full story
Ticking Away is a watch face inspired by Pink Floyd's Dark Side of the Moon: a prism splits light into a rainbow, the minute hand is a ray of light and the rainbow points at the hour. It's written in Zig so it can run in the browser, on a Raspberry Pi Zero 2 W driving a 13.3-inch e-ink wall clock, bare-metal on a Pico 2, and eventually on the Pebble Round 2.
The author built it with Claude Code but kept ownership of the code: Claude iterates quickly, he makes the architecture decisions and reviews every line of the core library.
