For just a few minutes a day this clock is shaped just like a cube. However, as time moves onwards it starts to change shape as the various sections rotate around an axis. When it gets around to 12 again the clock is cube shaped.
The largest triangle is for displaying hours while the medium is for minutes and the small triangle on the edge represents seconds. The cube clock costs just shy of $12 from Chinavasion.
