Abstract: A novelty device, which may be portable and connected to an article of clothing, includes an antenna that receives an operating signal carrying an activation command. A receiver within the novelty device is coupled to the antenna and demodulates the modulated operating signal to produce an operating signal, which in turn, is decoded by a decoder to detect the presence or absence of the activation command. An operator-controlled signal source sends an activation command to a transmitting unit, which in turn, modulates the activation command to provide a modulated operating signal to one or more novelty devices via an over-the-air channel. When the decoder detects the presence of the activation command, the decoder operates a switch to activate an indicator, which may produce lights, emit sounds, or perform some mechanical action or any other visual or audio effect.
