The lights can be energized to produce light beams as the carts move.

The carts, or selected carts, can be controllably moved at a selectably variable speed or speeds and/or in a selectably variable direction or directions while the lights are energized to produce the light beams. The lights themselves can be controllably moved with respect to their respective support carts, to controllably pan, tilt, swivel, etc. each light as the carts move, thereby facilitating production of a wide range of illumination effects.
