Each cube is made of six faces of cyan, magenta, or yellow mylar. In every case each face has one adjacent face of the same color. Each cube is placed next to another that is either an inversion or a rotation of its pattern. Through this arrangement, the subtractive colors produce the additive colors (red, green, and blue) as the viewer looks through the sculpture. This process is constantly changing as the viewer moves around the space observing the array from beneath.
