The Flow of Time

The Time Flows clock is an “interesting” clock because it’s haunting how the hours and minutes trail behind. Problem is, even with the animation (hit the jump), I still have no idea how to read it. Any ideas? Here’s what the designer said; “This clock lets us know the hour and the minute but all the unncessary things.
There is a circle board in the middle. Only the 1/4 part of the whole is colored. The hour and minute hands do not exist. The only thing that turns is the circle board. Through that we can know the time.”
