Lichtspiel: Opus III (1924) | Experimental animation by Walter Ruttmann

“Walter Ruttmann (28 December 1887 – 15 July 1941) was a German film director and along with Hans Richter, Viking Eggeling and Oskar Fischinger was an early German practitioner of experimental film. His early abstractions played at the 1929 Baden-Baden Festival to international acclaim despite their being almost eight years old. Ruttmann licensed a Wax Slicing machine from Oskar Fischinger to create special effects for Lotte Reiniger. Together with Erwin Piscator, he worked on the film Melody of the World (1929), though he is best remembered for Berlin: Die Sinfonie der Großstadt (Berlin: Symphony of a Great City, 1927). During the Nazi period he worked as an assistant to director Leni Riefenstahl on Triumph of the Will (1935). He died in Berlin of wounds sustained when he was working on the front line as a war photographer.“ - from Wikipedia I do not own this.
