I finally clipped my nails, and got an animation test together. The animation is a rotoscoped painting of a composited image (put together using photoshop, then stuck a sheet of transparent film to the screen, and painted on it with acrylics.)
It's way too jumpy right now, so I think I'll have to simplify, and work in more layers.
Does it look to you like the paint is just a photoshop trick?
