Digital Effects Inc. was an early and innovative computer animation studio at 321 West 44th street in New York City. It was the first computer graphics house in New York City when it opened in 1978, and operated until 1986. It was founded by Judson Rosebush, Jeff Kleiser, Don Leich, David Cox, Bob Hoffman, Jan Prins, and others. Many of the original group came from Syracuse University, where Rosebush taught computer graphics. Rosebush developed the animation software APL Visions and FORTRAN Visions. Kleiser later went on to found Kleiser-Walczak Construction Company, which experimented with creating synthespians and made the animation for Monsters of Grace.
