The NYIT Computer Graphics Laboratory was a research facility located in the Gerry House of the New York Institute of Technology between 1974-1992. At the CGL a variety of accomplishments were made such as the invention of the alpha channel as well as the development of computerized 2D animation.
Living Above the Mouse's Ear is a short film created by Duane Palyka and Hank Grebe, artists and animators of the lab. It was a joint effort between the Computer Graphics Lab and the 2D animation studio, which was originally founded for the production of NYIT's 1975 film Tubby the Tuba. Animators a part of that team include John Gentilella and Francis Glebas. Mouse's Ear was mostly animated on paper before the drawings were scanned and lined, colored, and composited digitally. The film was originally presented to Vestron Video in 1985 or 1986 for possible distribution, however it was rejected and never saw a public release or screening.
This film was provided anonymously.
