there's a Pizza Hut commercial airing in the states in which the aroma from the pizza snakes under a guy's door, tantalizes him, etc, etc...

My question is: how's this done and can LW/Mac do this?

It looks as though a smoke shader or smoke body was pathed along a spline or path, and both animated, but the smoke was so articulate - almost behaved like a hand at the end of the 'snake' (the end of the smoke in the guy's apartment).

any theories?
