Light as a Medium in 20th and 21st Century Art. With over seven hundred color illustrations of works by all of the important light artists -a new standard work on the subject.More than almost any other medium, electric light has revolutionized and democratized our world. Today we live in cities and gardens of light, and for almost a century, artists have been working with light bulbs, fluorescent and neon light, glowing LEDs, and powerful spotlights. This comprehensive publication offers a broad overview of the development of this genre, from the pioneers of light art in the 1920s and the immersing and interactive environments of ZERO, GRAV, Gruppo T, and Gruppo N, to the early light artists from Europe and North and South America. Outstanding contemporary productions -with their profound illuminated spheres, ironic cross-references, and fascinating plays of filigreed light- complete this glowing spectrum of explorations of artificial light.
