Moving Time

I just found the following clock, and absolutely love it. It throws commonplace to the side, by asking the question, what if the clock moved instead of the hands?

The clock works by rotating so the ball moves up the spiral as time goes on. Time is given by the location of the ball. When the clock strikes 12, the ball falls through the top hole and down to the 12:00. Brilliant!
