David sez,

"Almost two years ago, I came up with a concept for a 'Bulbdial' clock. Instead of physical hands, it has three shadows cast by a series of rotating lights indicating hours, seconds, and minutes.

Nine months ago, Evil Mad Scientist Laboratories developed a working model using three rings of LEDs.

Now Bulbdial Clocks are available as a kit from EMSL. They did the hard work on this, coming up with a cool Mantel Clock implementation in various styles. You can get one at their site here."
