Feature film — 1936

The Equation X + X = 0 (1936)

“If abstract films are really abstract films… they deal exclusively with those abstract relations that can be expressed in terms of shape and motion” wrote Robert Fairthorne in Film Art in 1936. A mathematician and information scientist, Fairthorne saw aesthetic potential in an animation made as a teaching aid by Salt, and proposed this collaboration. (Tate.org.uk)
