Check out this cool Digital Analog clock by Alvin Aronson.

Cool Gadgets - The Digital Analog Clock

Each of the seven segment displays mechanically move on the minute to display the current time. It does this by moving mechanically each of the segments backwards and forwards in to the background.

Check out the video of it in action.

This is a very cool clock, I would love to see this go into production, I would definitely buy one.
