@rain_storm: I haven't seen that demo before, very nice.
I've always liked the glow/gloom effect, it looks fantastic. How would you code it though?
I was thinking...
1) Draw lots of bright - Like maybe change each pixel intensity from 0.0 to 1.0, to something like 0.0 to 2.0 but have a cut off at 1.0.
2) Then post process the 2d image, by blurring it vertically, then horizontally.
Does that sound right?
