sorry for yet another 'looking for' thread...

has anyone come across a set of liquid materials/shaders? I'm particularly looking for ones which approximate to: beer, milk and muddy water...

Also, and this is quite an odd request, lol, I'm looking for a prop (esp morphing) that simulates some kind of 'sticky' goo stretched between two surfaces  - sort of the thing you'd get if you put something sticky between two objects and pulled them apart so that the bit in the middle thins and stretches (...lol, it's for a yucky alien type scene!)

thanks for any thoughts! :) :) :) :) :) :)
