From Ironic Sans:
I think we can all agree that sundials pretty much suck. … 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. In the model illustrated above, the light sources are each attached to a ring which rotates around the pole. The innermost ring rotates once per minute, casting a “second hand” shadow. The middle ring rotates once per hour, and casts the “minute hand” shadow. And the outer ring rotates once every 12 hours, casting the “little hand” shadow.
It’s funny how almost all the comments go, “I could build this in an hour.” Let’s see it, then! Skimming, it seems like only one person actually did make one — many years ago, to boot.
