With all of our complicated and complex technology it’s easy to forget that most began as something primitive and simple. Take the clock, for instance. It began as a simple and uncomplicated sundial. The problem is that the sun is not always out and a single hand only gives you a rough estimate of the time.

Today we need just a little more accuracy. The BulbDial Clock takes the sundial and updates it by replacing the sun with three lamps that rotate around a central pole. Shadows are cast for hours, minutes, and seconds. It took somebody awhile to figure out a good upgrade to the original time-telling gadget, but better late then never. It’s just a concept at the moment, though.
