Thirteen oscillating spheres of steel are connected to a matrix with a rubber band. A bar with a magnet on each side controls the action of each of the system elements. Once a sphere is connected to the bar, a motor activates its oscillation as long as the bar detaches an rebuilds a new connection to another sphere.
Each module has its own simple program logic and there is no main program which controls the system from the outside. No random or chaos must be simulated, because the always rebuilt physical structure of the sculpture becomes its own analogue program for non-linear behavior. Therefore the system produces complex behavior, although its structure and rules are very simple.
