Supermarionation

Supermarionation (a portmanteau of "super", "marionette" and "animation") is a puppetry technique devised in the 1960s by British production company AP Films. It was used extensively in the company's numerous Gerry and Sylvia Anderson-produced action-adventure series, the most famous of which was Thunderbirds. The term was coined by Gerry Anderson, possibly in imitation of "Dynamation", Ray Harryhausen's stop motion technique.
