When most of us consider impossible-to-use timepieces, Tokyoflash is the first brand to come to mind. Well now there's a worthy challenger, as the Chronochrome probably can't be deciphered without a cheat sheet.
Chronochrome actually displays time in simple 00:00:00 hour/minute/second format, but each number is represented by its own colour. Sensibly, these numbers follow a pretty standard chromatic logic. And for those who don't want to sleep next to a whole Skittles bag worth of bad dreams, the clock doubles as a nightlight, displaying each digit in pure white.
