Chromochrome – like a Tokyo Flash watch for your desk
Chromochrome has “a colourful interpretation of the time” according to the manufacturer. Complete incomprehensible, but colourful. In their words, it “tells the time with its six luminous coloured rings representing the six digits of the twenty-four hour clock, starting at 00:00:00 (midnight)”, so basically, each digit is assigned a number, and you have to memorise those colours in order to make even a guess as to what time it is.
It can also work as a nightlight and a mood light, so should you decide telling the time is too much effort, it does have other uses.
