“Kitty” is one of the first computer animations ever made: It was produced in Russia in 1968 under the direction of one N.Konstantinov, who led a team of physicists and mathematicians to produce something that looks a bit like an ASCII art flipbook today, but must have been remarkable at the time given the state of computing technology.
From avatarlemon’s YouTube description:
Soviet computer animation was made in 1968. A group of russian physicists and mathematicians with N.Konstantinov in the head of it created mathematic model of the cat and its moving and realized this model in the program for the computer “BESM-4″. Computer printed hundreds of frames on the paper using alphabet symbols and then they were converted to the cinefilm.
