Video feedback emulator generates gorgeous glitchy art

Thea video feedback emulator offers a vague memory of fooling with video cameras and a strong flavor of crisp and fractal generative art, The results lurk somewhere between the decades. Click and drag your results for wild (and often brightly-flickering) variations. The creator explains how it works. [via Github]

What weve found most interesting about video feedback is: the sheer complexity of the images it produces through such simply-defined and implemented spacemaps that really only have to do with the relative positioning of two rectangles. Its somewhat intuitive, but always surprising.

This is all just scratching the surface of the mathematics behind the patterns that video feedback is capable of, but hopefully its good enough for a start!

P.S. Youll notice that many of the interesting patterns contain regions of diverse sizes. That is, they appear to have a broad range of spatial frequencies. Whats up with that?
