The lighting circuits pulsate to the beat of the audio signal.

Abstract: A set of color gages for assisting in selecting harmonious color combinations in accordance with those found in nature and the method of using such gages. In nature all colors can be classified into one of three groups called Solis, Aero and Aqua.
