Abstract
A display device wherein decorative objects are immersed in a liquid-filled housing which is rotatably mounted on a base and driven by a windup music box mechanism through a transmission assembly so that rotation of the housing relative to the base in a first direction winds up the music box mechanism which, during unwinding and the production of music, causes the housing to rotate in a second opposite direction.
