For a very brief moment of time each day, the Time Cube is a complete geometric cube block. The rest of the time, the clock is a geometric abnormality, dedicated to making time reading in need of a mathematical proof.

The clock forms star-shaped shapes when it is not 12 a.m. or p.m., with a series of layered triangles revolving around the base. The large triangle displays the hour, the medium triangle showing minutes, and the smallest triangle revolving to point to the correct time, acting as the second hand. Get your own for only $12.
