Snow and Rain Effects

[WILL]

Does anyone know any good snow/rain effect tutorials?
Articles reffering DelphiX would be prefferable

I may have my old Snow Demo laying around somewhere. It was simple and used DelphiX actually. I think I added wind to it, but really it's nothing at all to add. Just add some x-axis movement to it. Really falling snow is just random left or right as it drops slowly along the y-axis each 1 pixel.

Rain on the other had I imagine would require a faster falling rate and no drift (x-axis) rate other than that or the wind. You may have to represent each rain 'drop' as a line and of course having some transparency would help the effect along too.

Lemme see if I can find that demo. (There is one already up somewhere on PGD for FPC and NDS in a Christmas Demo though! )
