Abstract

A bi-directional communication system communicates between a control station, which receives and outputs control signals, and one or more display cabinets. LEDs illuminate objects disposed about the cabinets. Addressable nodes interactively communicate with the control station and selectively operate the LEDs, each node being coupled to the control station and to associated LEDs.
