The Superplexus is the brainchild of maze obsessed Michael McGinnis. The device is a rotating three dimensional marble maze. Like the classic marble maze the goal is to guide the marble to the end of the maze by tilting the maze. Unlike the classic marble maze the Superplexus is spherical and can be rotated 360 degrees freely in any direction.
One of several iterations of the mass market version, the Perplexus.
