The old art depicted space as uniform and enclosed. The new art perceives space as organic and open. The old art was an object. The new art is a system. The configuration of the movement is more important than the shape of the object. The message of a kinetic and luminic work is the light and movement it produces. It has no other message. It has no meaning besides movement.
