displacing smoke

Hey...anyone have any good ideas how I could displace a layer of "smoke" as if something was passing through it. The shot I'm working on is a boot stepping into the foreground. The idea is for the frame to be covered in smoke and for the boot to step through it, hopefully blowing some of the smoke away while it does so.
thanks in advance.

Sure do -- shoot it that way. You're in for a whole lot of frustrating work if you try to do it in post. Sometimes practical effects are best. If you still have to get the boot shot, it especially makes sense to do it that way.

LOL. Dave's right. You could try an evolving fractal noise, with a moving greyscale boot as your displacement map for your object, but it's never going to create the eddies and curls you get from the complex fluid simulation from the stock library of 'God's-green-earth.' :)
