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 pixel-based, and show that it can result in stationary fractal patterns such as von-Koch snowflakes and Sierpinski gaskets.Keywords
