Answer» INTERESTING idea.... http://www.ironicsans.com/2008/03/idea_the_bulbdial_clock.html Quote I think we can all agree that sundials pretty much suck. They only have an hour hand, they don’t work at night or indoors, their accuracy changes with the seasons, and if you happen to LIVE in the Southern hemisphere they run backwards. And yet, we all would love to be ABLE to tell the time by looking at shadows, right? That’s why I’ve come up with the Bulbdial Clock. The Bulbdial Clock has no HANDS — just one pole in the center of the clock, and three light sources of varying heights which revolve around the pole casting shadows. Huh. That is cool and a good idea.cool idea, but i cant see that taking off. it requires 3 moving rings. the more moving parts = more prone to BREAKAGE. more moving parts also = more expensive.Did you check out the comments on the blog? Some people thought of using LEDs arranged all the way around the circumference... In that case there would be no moving parts...I could see how that would work. Neat clock!
