Roger Titley is a puppet maker I found who makes life sized puppets with realistic movement. He does work for live performances but performances out of the theatre as well as in.
He has a unique plain style. He uses a sort of lightweight craft foam for his designs. A key feature of his designs I would like to take forward are the mechanics behind movement of the dinosaurs neck and elephants trunk. he uses segments connected on a flexi spine to create the movement- simple but very effective.
