Wallace and Gromit

I love Wallace and Gromit. I was thrilled when we watched the wrong trousers in class. I used to watch that film when I was younger. Claymation is an awesome art form and other than the small stop motion animation I worked on for this class I have never really experimented with it. Like Dr Torre was saying it is one of the most personal art forms because all of the clay is shaped by hand so you can in fact see the artists fingerprint on the art. I am curious what sort of clay and structures they use in pieces like wallace and gromit because they are so consistent with the shaping between scenes. If anyone has a making of wallace and gromit or anything like that please let me know!
