This film, named Vol Libre, was presented by Loren Carpenter at the SIGGRAPH computer graphics conference in 1980. It is the world’s first fractal movie and utilizes 8-10 different fractal generating algorithms. After that presentation, the author was hired by Lucasfilms and used an antialiased version of the same software to create the fractal planet in the Genesis Sequence of Star Trek 2, the Wrath of Khan.
