Ron Cooper is among the pioneering California-based Light and Space artists, so-called because they broke beyond the bounds of the physical object to experiment with the manipulation of light and space and their effects on perception. Cooper works with variously colored fluorescent lights, as well as materials like glass panels, resin, and fiberglass that hold, refract, and reflect light. Though his vocabulary is Minimalist —he crafts cubes, rectangles, and circles out of the interplay of light on the materials he uses—his works are luminous, insubstantial, devoid of mass and solidity.
