So, I'm pretty confident that this just reserves space in VRAM for a finite number of "frames" and loops through them, and concurrently, adds new "sprites" to those frames. Am I correct?

Impressive nonetheless - kudos!

Actually I don't deserve all the credits.

I stole the idea from an old megademo on the Amiga that had me floored back when it came out in 1990. It contained a section where the Amiga was apparently animating a sheer unbelievable amount of "bobs" (blitter objects) whereas previously the Amiga topped out at animating around 300 or 400 "bobs" or so.

Here's a video of what I'm talking about: Skip to part 5, starting at 18:52 :

The grin on my face was pretty big when I eventually figured out how they did it.

And now the same effect runs on the commander X16 ?
