That's a neat effect... Are you using my toon shading stuff? I forget if I put it in the code archives or not. I did that sort of effect myself in my Tank Game. I think it's a pretty well known trick one can do with spherical environment maps. In my Tank Game, I used the effect on an add blended object to make a hemispherical energy sheild, like one might see on Star Trek.
It doesn't really look like an infrared effect though. It looks more like an X-Ray. Infrared looks more like a bright red person with orange spots around their eyes and such and blue coloration on cold stuff in the room around them. It doesn't make the edges light up like that. Of course I'm talking about a full color infrared view. It would look better to have a red color as you said and just use a black and white image. Or maybe some kind of hybrid. I wonder what mixing an infrared view with a color view might look like.
