Abstract

Video feedback occurs whenever a video camera is directed at a screen displaying the image currently being recorded by the camera. It can be observed in everyday situations, for example at sporting events when a stadium’s display screen comes into the camera’s view. Here we consider how this simple physical process is affected by the fact that monitors are pixelbased, and show that it can result in stationary fractal patterns such as von-Koch snowflakes and Sierpinski gaskets.
