This clock works in binary There's two hours in a day, 2 minutes in a hour, and so on The big, short hand tells you what half of the day you are on, the next hand tells you what half of that half you are on. So If it's 8 o clock, you're in the first half of the day, but the second half of the morning so the first two digits of time are 01...
It's kinda satisfying to watch
