Rhei
Time told through geometry and motion
Rhei is a gallery of clock faces where time is encoded purely through shape and motion — no numerals, no hands, no labels. 30+ designs across four categories: 6-hour, 12-hour, 24-hour, and calendar. Each uses a different visual language — rings, arcs, grids, bars, falling shapes. All clocks run live in the browser. A time scrubber lets you drag through a full day to see how each design reads at any moment. Built with vanilla JS/Canvas. One lifetime price, no subscription.
I've been fascinated by the idea that time doesn't need numbers to be readable — that pure geometry and motion can carry the same information.
Rhei started as a personal experiment and grew into 30+ distinct clock designs. Each one explores a different visual language: rings, arcs, grids, bars, falling shapes. No numerals anywhere.
The time scrubber on the site lets you drag through a full day to test how intuitively each design reads. Some surprise you.
Would love to hear which designs communicate time clearly to you — and which ones just look nice without being readable.
