This is a simulation of a new kind of geek-clock: Hours, minutes and seconds share the same pair of 7-segment LEDs. Hours are displayed with red, minutes with green and seconds with blue LEDs. The colors will add up, but you still can identify the time, if you know about the additive color model.
The clock could be implemented in hardware by using my 7-Segment RGB-LED-Hack. The idea is taken from matthiasr on the Hackaday forum.
