I imagine it would have to be some sort of impractically large closed-loop steam system, probably running around the perimeter of the pot, with a rotating paddle inside. Not at all practical, but it would be neat.

At a rolling boil you could probably get the pot stirring itself with surface geometry. Bubbles boil upwards, so putting the right fin shape should get it spinning. Seems like it would require a bunch of machine work so it would probably be prohibitively expensive to make.
This exists. I tried to find a link or video but it seems to have disappeared.
Edit: Here’s a page on it. It’s from 2012 though, I guess the idea never really took off.

I had a friend with a similar pot (might have been the same one shown there) and… oh my god, it was impossible to wash. Just awful. Neat to watch but oh man, never got used after that.
Why? It just looks like bumps, no? Did a sponge not get in there?
They’re pretty pronounced so there’s deep overhangs + not much working space on the interior. Fine to wipe down sure, but anything requiring even a little scrubbing was miserable and a standard dishwasher’s spray was blocked by the geometry. We tried to use it a couple times because it was neat but then everyone in the friend group collectively gave up on it as being very not worth it.
Is it this one? https://www.youtube.com/watch?v=91yoFz5XFqY
Looks like it!
Can you imagine cleaning such a monstrosity though?
This already works with noodles if you place them vertical the middle and then twist them and let them fall in a spiral pattern leaning against the edge of the pot. As they soften and fall in they will spin in a toroidal shape powered by the bubbles.
