The magnetic bouncer is a unique computer interface based on the repulsive force of magnets. Magnetic attraction is all very well, but is a bit limited. Bringing two like magnetic poles together so that they repel, however, is fascinating: you can feel the magnetic field as you move them closer together and around one another. A simple way to demonstrate this effect is with ring magnets on a pole: they will sit still with the upper magnet suspended in mid-air, but disturb them and they bounce around in a most satisfying manner. We wanted to be able to capture this bouncing action and feed it into our computer to act as a controller.
