I’ve seen a similar low-tech version of this clock (sorry I can’t find a link). You setup two jars. Fill one with 365 * (years of life left). In the morning you move a single bead from the full jar to the empty one. It’s supposed to help you visualize “spending” your days, and encourages you to live them more deliberately.

I recall reading about this technique as used by Chris Crawford, a veteran video game developer with a lofty goal. (Intriguing article if you have the time.) https://kotaku.com/30-years-later-one-mans-still-trying-to-f...

Yep this is the source.

> Chris Crawford owns 29,216 small plastic beads. Each bead is one of eight colors, and there are 3,652 beads in each color group. One bead represents a single day in Crawford's life. Each color group, therefore, represents one decade. The yellow beads are his childhood. The black beads are his teens. The greens are his inexperienced twenties, the oranges his restless thirties, the navy blues his settling forties and so on, all the way up to bead 29,216, which will represent his eightieth birthday.
