There is a Wikipedia user who made lots and lots of gif for Wikipedia and if you click the user profile you see them all.
Can't remember though.

Holy shit, I made that. Here, have two more, they're pretty much the same, though. If anyone is interested, it's the simulation of a chaotic system (a Duffing oscillator). I first track the phase space throughout time, and then take the Poincaré section for several different periods in time.

However you want to. Right now, I just put a timer/lifespan along with an early-end condition that'll skip some time. On the interim, it changes states that are each individually written with their own mathematics, conducted based on windows of time. For change in time less than 5 seconds, it does the first attack, then in the next 5 seconds, it gets rid of phase-1 bullet origins and does the second attack, et cetera. Vector positions for the bullet origins, bullet spawns based on the origins' positions, having them all move with respect to their own individually assigned time t variables, and not getting rid of the bullets until they go offscreen or something ends their lifespans.. those are all common fare in making bullet-hell toys.
