The Bob-clock
The Bob-clock is a wall-clock which uses 60 multi-color LEDs arranged in a circle to represent the small and big arm of an analog clock. If desired, it can also display the seconds with a third color. The image above shows the Bob-clock as it currently looks.The blue light signifies the hour-hand, while the red one is the minutes, so the image above the time is about 10 minutes to 4.
