Don't laugh; I want to create the visual effect of a cat walking across the screen! Seems like maybe the old Pink Panther movies had something like this in the cartoon introduction to the movie... I want to show the bottom pads of a cat's footprints appearing one after another in a pattern as though the cat had stepped in paint and is walking on the screen.

Obviously, as each new step appears the previous footprints would remain in place. I thought of having multiple video tracks, with an individual graphic of a cat's foot on a transparent background on each layer. I also thought about creating a full screenful of cat tracks and revealing them one at a time w/Bezier masking and keyframes.

This doesn't have to be terribly realistic. In fact, the more 'cartoonish' it looks, the better. Does anyone have any ingenious ideas about how to do this?

Thanks!
