The different densities will cause the ior to be different, refracting 
light...maybe not always away from the center. However, this is variable 
ior, a pretty difficult and processor-intensive effect.
Also, I don't know how much of an effect it would have...it could easily 
be barely noticeable. You can often see shadows from the "turbulence" of 
a flame, but they aren't very distinct.
Back to the laser-beam experiment(I wish I had my laser pointer!), to be 
thorough, you would need to use lasers of several different wavelengths 
to get the actual color of scattering...actually, it might be better to 
use a focused, high intensity white light instead of a monochromatic 
laser...
