Prisms

Prisms shows white light (treated for the sake of simplicity as a mixture of seven sharply-defined colours) refracted by a ring of rotating prisms. The optical properties of the prisms are chosen so that one of the wavelengths will be refracted around the ring when the prisms are correctly aligned. The rotation slows whenever light rays connect several of the prisms, either in the ring formation, which is always present, or in any other serendipitous pattern.
