Video Feedback

Video feedback occurs when a camera looks at a display and tells the same display what it sees. Depending on the settings of various controls (e.g., zoom, focus, contrast, brightness, rotation) as well as on things beyond control, such as intrinsic noise, the camera-display system can produce an infinity of patterns – stable and temporally repeating images, spatial “dislocations”, Farey sequences, chaotic attractors, etc.
