A small gague of film used in home movie cameras, to make short films or animation. It comes in square cartridges that cost about $10, and another $10 to develop, and last for 5 minutes, so unless you're doing something special, you'd probably choose to use video. Super 8 film was an improvement on old 8mm film, which was just 16mm film chopped in half. A good super 8 camera will let you take pictures one frame at a time, so that you can create claymation or other such wonders.
