Early experimental computer animation through mathematical modeling of a cat’s gait. Evidently, equations were written to model the basic skeleton form of the cat and its walk, and the computer was used to generate a shadow-like projection printed frame by frame onto paper using ASCII-like characters (this animation was done in 1968 on a Soviet BESM-4 mainframe, so I’m not sure what character set they’re actually using here). The result could then be filmed, inverted, and manually cleaned up. Not exactly something that would really take the animation world by storm, but it’s an interesting usage of mainframes for art.
