Spin Class

Spin Class uses the doll torsos remaining from the other "Doll Part Pieces" to make a simple model of magnetic spins -- called a Spin Glass in the real world. Stepper motors rotate the torsos on axis and as one rotates its neighbors try to maintain a balance of direction. The system eventually settles into a stable pattern, but eventually noise interferes and a torso will flip, setting the whole thing in motion again. A sensor at the bottom detects proximity and adds more noise the closer someone gets.
