This geiss effect is just a variant of the classical fire effect. It's very easy to create,
you can check out the source code on my web site www.Alias25.com.
If you want more details about it, just ask me =)

very nice indeed - i downloaded the demo, nice work.
tim: this isn't a new technique, it's been used many times before... it basically consists of drawing something, zooming in a bit, then drawing the next frame over that, and so on. it's fast, but it couldn't really be used in a game except for something like... a sort of simulation of being very drunk or being in a dream (and, no i'm not very drunk in *all* my dreams!) - which would be awsome!
Well, you could find uses for it in a game as a procedural texture on a magic spell or something for an RPG. Like toss this texture on a sphere or something--I dunno. Sure, it's not realistic, but it could be a neat special effect procedural texture.
Mmhhh yes, that blitter feedback trick, although this is a particularily nice version :) Do you use bilinear filtering and that artifacts are caused by JPEG quantization or does it happen because you don't filter the thing when scaling? Just curious.
