Abstract
Disclosed is an electrically-operated ornament travelling on a rail capable of explaining the free quadrants described in the Mobius Theorem. The ornament mainly includes a three-dimensional endless rail supported on a set of supports. The rail includes at least a twisted and turned part and a non-twisted part. Two parallel metal wires extend through a full length of the rail on both surfaces thereof. A controller is used to supply current to the metal wires and to control the magnitude and flowing direction of the supplied current. A moving body having rollers made of permanent magnetic material is magnetically attached to the metal wires. A transmission mechanism in the moving body is powered through the controller to drive the moving body to travel, back, or stop on the endless rail.
