ABSTRACT:
Accordingly, a display system is provided whereby visual elements can be independently transported not only around but also parallel to the display axis. The display comprises a central shaft; carriages mounted along the length of this shaft; and visual elements borne by the carriages. Each carriage has a circumferential drive train which can propel it around the shaft, and an axial drive train engageable with a visual element such that the visual element can be passed generally parallel to the shaft from one carriage to an axially adjacent carriage. Ideally, the system is controlled by a computer system which may be programmed to move the carriages and visual elements in complex configurations.
