Milton Komisar began creating light sculptures in 1973. His works employ sophisticated computer controlled lamps in combination with solid acrylic rods. The acrylic rods extend from "nodes", which give the light and color. Each node contains a red, a green, and a blue lamp, and these colors can be combined in varying amounts to make all the hues of the spectrum. The physical constructs provide a canvas on which the artist has choreographed an everchanging rhythmic and harmonious display of color.
