Mathematics Application Group, Inc., aka MAGI, was an early innovator in the area of computer graphics. They are particularly well known for their work in television and film. They are credited with the first computer-generated imagery television advertisement, for IBM. Perhaps their most famous work is their lightcycles and tanks for the film Tron (1982). Technically, they were the first production house to use ray tracing to generate images, as well as constructive solid geometry techniques.
