Plasticine
Because of its non-drying property, it is a good material for stop-motion animation. It has been used for several Oscar-winning films by Aardman Animations (Nick Park). The brand-name clay is sometimes mentioned in British music, such as the "plasticine porters" in The Beatles' "Lucy in the Sky with Diamonds",  the Oasis songs "Little James" and "Shakermaker", the Placebo song "Plasticine", and the Thom Yorke song "Plasticine Figures".
