This is an old sculpt that I dug out and photographed today, it's Boris Karloff from "The Black Cat." It was done in Sculpey and very tiny - about 3/4" high.
At one point during the lengthy production of "Extreme Man & Insane Boy" I considered animating them in clay. Here's the sculpts that I came up with. They're pretty old now and they've gotten kind of dusty. Also the irises were never painted.
