Above is a cgi lizard shaped smoke simulation i did on blender 3d. It is very simple yet quite effective. It is a basic shaped smoke simulation with a turbulence forcefield effect on it to give it the puff and wipe off effect.
It was created using a lizard mesh, i got off a free model site, and a basic smoke simulation. The turbulence was animated in a right to left motion to give the final effect.
This would be good as a title or logo effect or image as well as a film / tv visual cgi effect if it was keyed and animated more. Also for the next time i do this type of project again i will experiment much more with the smoke domain settings and turbulence effects to get the better and different effects.
