Video Feedback Overview Video feedback is the process of pointing a camera at the screen displaying the camera's output. This creates a feedback loop of images infinitely repeating onto and over themselves creating interesting patterns. An initial curious result has become a studied phenomena that relates to other sciences such as cellular automata, reaction diffusion and non-linear dynamics. This page has information on simulating video feedback, examples of real video feedback and links to other websites with further information about video feedback.

Simulating video feedback The following movie is a sample of some results from attempting to simulate video feedback. Created with Visions Of Chaos. See SimulatingVideoFeedback.pdf for more details.
