I've been wanting to figure out some kind of way of generating some kind of smoke, cloud, mist, plasma and liquid like textures in Quartz Composer. There are already some pretty decent ways of going about some of this, especially clouds, but I am most interested in getting "smoke" and "liquid" going...

As I have experimented, I don't think that there is only one way of going about it that is correct in all situations.

This was achieved by generating particles inside of a GLSL shader, and adding blurs. It uses kineme particles, v002 blur, and a paraboloid shader that was originally straight out of the desaxismundi solids example that toneburst did for quartz composer. The shader is fairly well changed up at this point, just from tweaking it through trial and error.
