Powers of Ten,
Made by the Office of Charles and Ray Eames for IBM. 1977. Available from Pyramid Films, P.O. Box 1048, Santa Monica, California. Excellent! The film was done in collaboration with the book.
The Invisible World,
Natural Geographic Society Video, 1979. Distributed by Vestron Video, P.O. Box 4000, Stamford, Ct. 06907. Travel beyond the powers of the naked eye into a realm of wonder and fascination. Each moment events take place that the human eye cannot perceive because these occurances are too small, too large, too fast, too slow, or beyond the spectrum of visible light. Well done!
