Jan Švankmajer (1982)
Dimensions of Dialogue is a 1983 Czechoslovak animated short film directed by Jan Švankmajer. It is 14 minutes long and created with stop motion.
The animation is divided into three sections. “Eternal conversation” shows Arcimboldo-like heads gradually reducing each other to bland copies; “Passionate discourse” shows a clay man and woman who dissolve into one another sexually, then quarrel and reduce themselves to a frenzied, boiling pulp; and “Exhaustive discussion” consists of two elderly clay heads who extrude various objects on their tongues (toothbrush and toothpaste; shoe and shoelaces, etc.) and intertwine them in various combinations.
