Instructions for creating a Stop-Mo armature without expensive casting, ball-and-socket joints, etc. The example they use is a dinosaur, end result looks as good as those on King Kong or Planet of Dinosaurs, tho the person who wrote the article probably already has some practice sculpting. Has links to other armatures.
