Certainly I remember seeing an nVidia demo that renders puffs of smoke 
in a glass tank.

The *motion* of the smoke was very, very convincing. The visual 
appearance of the smoke itself, however, was much less convincing. I'm 
not sure precisely why. Probably because to make it look right, you need 
global illumination, scattering and so forth.
