The founder of Pixar is a guy named Ed Catmull. But WAY before Pixar made their modern classics, Ed was a grad student at the University of Utah studying math, physics, and computer science. While he was there, he made a cool prototype of what was to come. You can check it out, it's a computer-animated 3D rendering of Ed's left hand, and some faces. But keep in mind, it's from 1972! Almost 40 years ago!
