OK Feel like a bit of a cheat now, but this is something I coded quite a while back when I was messing with blitz a lot. The effect hasn't really got a name so I just called it swirlies....
Anyways Instructions are on screen, probably best to press space a few times to see some different patterns..... and if you get a crap frame rate with the text on just toggle it off...
Enjoy, and sorry for the size of the file.... Hated blitz back then for the big exes, and now its back to haunt me..... (Source is included Enjoy!!!!!)
