This clock is a perfect cube twice a day. All the other times it looks like something out of Hellraiser.
The rest of the time one of the corners sprouts a series of triangles that rotate, filling the roles of hour, minute, and second hands. It looks kind of difficult to tell time on the thing, though pretty easy to lose yourself in the edgy 3-D shapes that emerge as the seconds tick by.
