Skip Sweeney was an early and proficient experimenter with video feedback. A feedback loop is produced by pointing a camera at the monitor to which it is cabled. Infinite patterns and variations of feedback can be derived from manipulating the relative positions of camera and monitor, adjusting the monitor control, becoming a swirling vortex. Sweeney and others were intrigued with feedback's ability to generate pulsing images like a living organism. He claimed he would "just as soon be a video rock-and-roll musician" and produce feedback as a performance instrument (Anthology Film Archives, 1981). Sweeney produced many variations of feedback and processed imagery, and is especially noted for his works incorporating dance and movement.
