I got to 1600+ sprites going - I couldn't watch after 10 as it made me kind of queasy. I wonder what the upper limit actual is.

Spoiler alert.



(there is no upper limit, eventually the counter will wrap around to zero I guess if you're patient enough. It's all an optical trick.)

It is heavily inspired by the classic Dragons Megademo "infinite bobs" trick [yt]https://youtu.be/3NhQGdXlkOE?t=1404[/yt]
It uses bitmap mode with a bunch of back buffers that it cycles.
