Go OK

Using a webcam and laptop, here is feedback from a digital source. Different parameters: rotation, refresh rate, color filtering, pixel size.. and more, affect the geometric patterns, image blurring and chaotic appearance and sometimes pulsation of the video motion.

This is a very simple first try. With some time and work, artistic patterns can emerge. I remember playing with this phenomenon a decade ago after seeing studies in analog video systems, but am happy to see it work in digital format.

James Crutchfield wrote an article on analog video feedback in systems more than a decade ago, and it was just great. Here is his site on other dynamic systems analysis and more.
