Laser sundial tells time anachronistically

This simple laser sundial uses a micro-controller, an Arduino board, and a laser level to tell the time using bright and magic laser light. A small motor slowly turns the laser on an axis, marking off the hours of our days as surely as old death takes our lives piece by piece.

Allesandro, the creator, includes all the schematics you need for making your own device and even includes a video showing the kit in action.
