There's nothing quite like taking a beautifully simple piece of technology and making it incredibly complicated, and few devices are quite as simple as a sundial. The problem is that sundials only work when it's sunny out, and their single hour pointer gives you only a pretty rough estimate of the time. That may have been fine back in the middle ages, but we demand a little more accuracy from our timepieces.

The BulbDial Clock gets around these issues by replacing the real sun with three lamps that rotate around a central pole casting shadows of varying lengths for hours, minutes, and seconds. The ironic thing is that the BulbDial doesn't work out in the sunshine, only in a dim place where you can see the shadows.

For now, the BulbDial is only a concept.
