Robotic Etch-A-Sketch Clock

This is a style of clock I have never seen before. This clock uses a laptop, circuit board and an Etch-A-Sketch hooked up to a couple of stepper motors. Each and every minute the etch-a-sketch is flipped upside down automatically, rotated right way up and then the current hour and minutes are redrawn on the screen with in about 20 seconds. At the minute mark this process is repeated.
