This is what a pinned superconductor looks like. Here is a video I made of some YCBO over a small magnet: https://nt4tn.net/random/superconductor.mp4 you can see it settle back back when I move it with tongs (until i push hard enough to get it to snap into a new orientation).

If I had a magnet that was much bigger than the superconductor it would look even more similar (less 'pivoty').

Excellent video, really very nice. I like it how you forced the flux pinning by punching a hole in the middle of the superconductor, that makes it all much more visible. You can practically visualize the fieldlines escaping through the middle and becoming an elastic pivot connected to the magnet.

If only all videos of LK-99 (and UFO sightings for that matter) came in such high, crisp resolution. Thanks.
