The Multi-Projector slide format was the formal presentation medium for museum exhibitions during the 1980s and precedes video and digital technology that is used today. It was a complicated installation, employing from six to eighteen slide projectors driven by a computer program that synchronized 35mm slides with the soundtrack. The result is a flip-book-like animation that can at times be surreal and sensual. The rich detail and saturated colors made possible with 35mm Kodachrome, makes for visual intensity superior to anything that could be delivered using either video or print. These narratives last an average of 10–15 minutes and were usually shown in a theater-like setting at the beginning of the exhibition.
