Plasticine was available when I was a teenager and started doing animation. I wanted to be like Disney, trying to film with plastic cels, but it was all too expensive. I didn't have enough money to buy cels, at least not enough to make more than four-and-half seconds of animation. But Plasticine was around, user-friendly and available to the masses. It was great because all you needed was camera, an Anglepoise lamp and a table. And you would make whatever you like come out of a blob of Plasticine.
