Creating smoke?

[Jonathan Gift]

Hi,

Now I'm new to this list and so don't know if this is appropriate... I'd
like to create some swirling smoke as from someone smoking and have
tried swirl, etc on a grey gradient but doesn't quite cut it. Hs this
been done and how? I'm ure it has, but the how is the question.

Sort of like the supernova, but for smoke?

Much thanks.

Jonathan
