Present continuous past

In Present Continuous Past(s) (1974) the image seen by the camera (reflecting everything in the room) appears eight seconds later in the video monitor (via a tape delay placed between the video recorder, which is recording, and a second video recorder, which is playing the recording back).
If a viewer’s body does not directly obscure the lens’s view of the facing mirror the camera is taping the reflection of the room and the reflected image of the monitor (which shows the time recorded eight seconds previously reflected from the mirror).
Thus the work highlights the device of the representation by integrating the spectators who become characters of the show they attend at the same time as others can observe them.
