This beautiful clock takes advantage of the fact that if you place a diagonal line on a rotating base, it'll trace out a hyperbola shape in 3D. The hours are marked on the clock, a nd whichever one the hand is pointing to will show you the nearest hour. An attractive adornment for any desk or horizontal plane, this is also a demonstration of the concept of a ruled surface. Oh, and it tells the time. The clock comes in a range of colours, and measures 12cm in height, with a base diameter of approximately 11.5cm. The clock is part-assembly (two simple clicks!) and comes with full instructions.
