Remarkable, but not really surprising or new. Classic illustration is sometimes called the "waterfall effect" en.wikipedia.org/wiki/Motion_a… No doubt it results from fatiguing of motion detector neurons in the retina or the visual cortex. It's a more sophisticated version of an afterimage: stare at something red for a while, then look at a white wall, and you will see a copy of what you were staring at, but in green instead of red.
No i know it's not surpprising or new - i was just surprised as it wasn't the purpose of the video. But i had just seen a programmed called mindgames which displayed exactly that effect so i thought i would try it on my video - and it worked - Yes i know the the effect where you will see the complemetary colour off what you have stared at
Have to admire the video anyway The blocky shapes really are 3D, and the rotation makes that apparent.
As I watch the video, I see an effect that may be peculiar to myself. Certain regions distinguish themselves momentarily from the rest of the image. It's hard to describe.
A few times, back in the days of analog broadcast TV, I could tune to a vacant channel to see the video noise, sometimes called "snow". After a while I would begin to see swirling movements within the snow. I can't account for that, except to assume that the snow wasn't really quite random, and some property of the noise was selectively fatiguing my receptors.
