Musgrave designed the initial fractal-based programs on which Bryce was based. His work was featured in an article in the January 1996 Scientific American (Playing Slartibartfast with Fractals; January 1996; by Gibbs), about fractal curves. The article described software that he had designed which would generate entire planets at random and allow a user to walk about that world, exploring mountains or forests, etc. The article mentioned that the software would find itself used in a computer game and that the randomly generated landscape would have to be populated with hostile aliens. Eventually, the software eventually became a commercial title called MojoWorld. Musgrave received screen credits for digital effects in the films Titanic, Dantes Peak and Lawnmower Man.
