http://bulbdial.com/ One minute in the life of a bulbdial clock, sitting on our window sill on a partly cloudy day. This is an "indoor sundial" clock that has three rings of LEDs that create shadow hands of different length on the clock face. While the camera doesn't capture it very well, the spots of light cast by the ultrabright LEDs are brilliant red, green, and blue.
