Nice contribution, quite helpful.

Since it's about more or less the same effect, does anyone know how to achieve a nice 'underwater' look? I mean "demo scene"-style actually, loads of those demos have these particles and sort of blurs and fog that really make it feel as if in some sort of underwater/dreamy/spacey place. I haven't achieved anything quite like it with 3dgs yet, if someone has ideas... please tell hehehe,
