A rotating disc consisting of four concentric glass prisms hangs from the ceiling. A spotlight with a beam exactly the size of the disc is focused upon it. The light is refracted through each of the prisms and projected as four rainbows as well as four white rings onto the walls. For every rotation of the disc, the projected rings pass a full 360° around the space.
