An artist's rendering of the "Kinetic Mosaic" preshow screen, also known as the "Radok Screen" for its creator, filmmaker Emil Radok "The Universe we know is one of dynamic forces -- its heartbeat sending a constant flow of energy coursing through the vastness. " Binding atoms into molecules and crystals - and stored in the cells of all living things - is chemical energy. "Unleashed in the motion of molecules themselves is heat energy. " "Sooner or later, present resources will not be sufficient for the world's energy needs. " The Kinetic Mosaic screen "unfolds" like a flower in the beautiful and dramatic finale of the preshow. An abstract scene from the Preshow's finale. The image echoes the pavilion's concentric-ring logo.
