The Bulbdial Clock - a high-tech sundial

The Bulbdial Clock is an electronic take on our oldest way of telling time - the sundial. Instead of relying on shadows cast by the sun, this timepiece features three layers of colored LEDs that rotate around the clock face, casting shadows to represent the hour, minutes and seconds.
While a traditional sundial displays only the hour, the Bulbdial Clock has three rows of red green and blue LEDs which shine a light onto the gnomon (or central object), creating the three “hands”. When the lights overlap a host of secondary colors are produced.
The picturesque clock is available in four case designs including clear front and also has optional USB connectivity for either syncing the time with, or charging from, a PC. For those with basic soldering skills, the Bulbdial Clock is available now as an assembly kit from US$65 at Evil Mad Science.
