The fucking wildest part is how they only appear to rotate a short distance, maybe 30deg or so, but there’s no seam in the loop. It took me a minute because when I would blink, it does feel like a jump cut, but if you can relax your eyes and keep staring it seems to somehow impossibly seamlessly continue moving a short distance in the same direction without resetting or completing a loop.
and then I started to see the short sides as being in front. Then I briefly saw the face of the universe, blacked out, then wrote this post.
