Making Smoke like Particle system

SomeKid's picture

I am interested in making a smoke like particle system. I have searched kinda deep into some of the threads, and found some info. I read a great deal of george toledo sample thread. And got that I need lots of Interpolation and a particle system to do any thing remotely interesting. I think that is what I got, hard to tell. George you do a good job of keep your work yours. Which i can understand 100%.

But so my real question is do I need Kineme3D or QuartzCrystal to make smoke in Quartz Composer?

Am I thinking about this right? Small particles. Lots of them, I am guessing. Some gravity. A pretty short lifetime, or long lifetime? Do i need an image of some sort to make it look more real?

Help much appreciated
