This retro video shows a demonstration of the animation software Key Frame, which was created by Marceli Wein and Nestor Burtnyk from the National Research Council of Canada.
The program, and the computer they're using, may look archaic by today's standards, but at the time they were the absolute cutting edge in computer animation.
And Key Frame played a pioneering role in the creation of vector art and animation programs, like Adobe Flash and Google SketchUp, that we know and love today.
