The Cabinet of Jan Svankmajer (1984)

The Cabinet of Jan Svankmajer is a 1984 British surreal short stop-motion film by the Quay Brothers, an homage to the influential short film maker Jan Švankmajer.
It is structured as a series of little lessons on perception at Prague in a form of a puppet simulacrum of Svankmajer, whose head is an opened book, to a doll whose head the masters empties of dross and refills with a similar open book.
