The Kinetichrome and Its Use of Polarized Light

The invention of Polaroid in 1938 opened up new horizons for artists, giving them the opportunity of applying the fourth dimension of time to their work. The author traces the development of his work with Polaroid from his early experiments, using a handmade cardboard slide viewer with two Polaroid discs inserted, to his current Kinetichrome projections, which utilize computerized control to intensify color and movement as desired. Biréfringent materials, the design for a slide worktable and the sequence used for the two polarizers are described.
