In PYROGLYPHS, fifteen (or eighteen) monitors are arranged in a circle on the floor facing up and inward at a 30 degree angle. The viewer stands outside this circle looking in.
Three channels of video program recorded on laser disk players provide one video and two audio sources each routed to a circle of video monitors with internal speakers (see drawing for assignment).The laser disk players are aligned by a synchronizer for synchronous playback. Each player at the end of its twenty-minute cycle automatically returns and re-synchronizes for a continuous performance.
