an attempt at foam/froth using a displaced cylinder with an alphamap.
file in zip.
I like that jowra - and I bet that is a lot more controllable than using emitters.
anyway I think I might need to go and do some more "Foam" research - shesh ! the things I do for my
art 
edit the png is just showing up as a white screen ? i've no idea what I've done wrong there ?
