Chris Musgrave, Infinite Loop (Deus ex Machina) 2004 A camera is rotated on its side and pointed into a television at close proximity. The camera feeds the image of pixels on the screen back into the TV’s audio and video inputs. The auto focus and auto exposure struggle to gain some coherence expected in an image, but cannot. The result is a fluctuating, oscillating signal. (Link)
