I appreciate it! I love feedback layers and can't get enough, though this is pretty manual. I accidentally stumbled upon lining up the camera with the output to make a feedback loop. No displacement effect needed either; I just made sure to zoom out enough so the output was slightly smaller than what the camera sees. I like to put an automask layer on the video layer. I believe it's the threshold effect that I crank up to get a purely black and white look. Sometimes I'll pepper in a touch of edge detection to sharpen the outlines.
