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.”
