AbstractA display device consisting of a plurality of rotating segments each carrying elements of a message or sign, each rotating relative to each other, the center of rotation of each being concentric to each other. These segments are driven by a series of planetary gear systems or their equivalent, arranged in layers, each driving the next. To these segments may be attached a plurality of auxiliary devices, all driven by the same mechanism, which can enhance the attraction of the device, carry elements of the message, etc. Each segment or auxiliary device can be of a variety of shapes, colors, graphics, etc. Segments can be nested or overlapping, totally or in combination in any relation to each other. Message can be continuously or intermittently scrambled and unscrambled.
