Clock based on the game Fez from Polytron.

It consists on four three-dimensional hands around a common center, each on a different side. Only the coloured hand correspond to the true rotation, the others are seeing sideways or backward. To rotate the clock so that all sides can be seen click on the 3 and 9 marks.

The meaning of each hand is adapted for convenience. White=seconds, Red=minutes, Blue=12hour, Green=24hour.
