The Bulbdial Clock displays analog time, without any motor, movement, or screen. The 72 LEDs cast shadow hands across its face, with red, green, and blue for hours, minutes, and seconds. It’s a beautiful effect, and the kit is not difficult to assemble, thanks to incredibly well-done instructions.

Last year David Friedman published on his blog Ironic Sans an interesting design concept for something that he called The Bulbdial Clock. That’s like a sundial, but with better resolution– not just an hour hand, but a minute and second hand as well, each given as a shadow from moving artificial light sources (bulbs).
We’ve recently put together a working bulbdial clock, with an implementation somewhat different from that of the original concept.
