Art shaped by neon and fluorescent light, its focus is illumination and color. Neon Sculpture suggests commercialization because its thin tubal lights are often used for advertising signs. Vardea Chryssa, stimulated by the lights of Times Square in New York City, is one of the pioneers of Neon lights in sculpture. Beginning 1962, she used illumination with and without color and subtle sequential lighting effects, usually in Plexiglas boxes. Joseph Rees, creating pop art objects such as tables, chairs and eye glasses, was also a pioneer in the use of neon. Other neon artists are Dan Flavin who works with commercial tubes, Billy Apple and Stephen Antonakos. "Phaidon Dictionary of Twentieth-Century Art"; AskART database.
