1. A display device for use in an environment comprising:

  • a display base provided with a plurality of indication units which illuminate when activated;

    a broadcast receiver-decoder unit coupled to the base which detects a non-specific broadcast receiver-decoder unit coded sequencing signal emitted by any one of a plurality of broadcast transmitters within the environment, wherein at least one of the transmitters is capable of transmitting a different coded sequencing signal from the sequencing signal transmitted by at least one of the other transmitters, and the broadcast receiver-decoder unit decodes the coded sequencing signal when the receiver decoder unit is within a predetermined vicinity of the transmitting broadcast transmitter to provide a sequencing control signal;

    a microprocessor control circuit coupled to said receiver-decoder unit and to said indication units and having a stored program, said program directing said control circuit to generate a sequence of output signals based upon said control signal, said sequence of output signals activating and illuminating said plurality of indication units in a sequence determined by said sequence of output signals to provide a predetermined visual display on any said display device that is located within the predetermined vicinity.
