An ornament has a frame. There is a central fixed disc attached to the frame and a picture of the central fixed disc. An annulus surrounds the central fixed disc and is rotatably mounted in the frame. A magnet is positioned in the annulus. Weighted figures are mounted on the rotatable annulus. The figures bear a relationship to the picture on the central fixed disc. A magnet can rotate the annulus by magnetic effect on the magnet in the annulus so that the weighted figures rise and fall as the annulus rotates to change the displayed scene.
