Abstract: A lighted display having a constantly changing image comprises a transparent container holding an aqueous suspension of delaminate vermiculite. A light source is positioned at a first surface of the container so that the light shines through the container and the liquid suspension within the container. First and second polarizer films are placed on opposites of the container with the first polarizer film being located between the light source and the liquid suspension and the second polarizer film being located between the liquid suspension and the observer with the films oriented so that the two axis of orientation are not parallel to each other. Transmitted, polarized light passes through and is modified by the plate-like particles in the suspension and is observed as an image generated by the display. Stirring means are also provided so the aqueous suspension is constantly in motion.
