Eugen Schüfftan (1893 - 1977) was the creator of the special effects for Fritz Lang's silent classic "Metropolis". His more radical experiments, utilizing custom techniques of optical printing with partially transparent mirrors, have never been seen.
In this 1927 experiment, Schüfftan transforms footage from a love scene from "Metropolis" into a Futurist-style study of motion.
