Musgrave designed the initial fractal-based programs on which
Bryce was based, and later worked on designing the Deep Materials Lab component of Bryce. His work was featured in an article in the January 1996
Scientific American (Gibbs, "Playing Slartibartfast with Fractals") which discussed fractal curves. The article also described software he had designed which would generate entire Earth-size planets using semi-random procedural 3D, and then allow a user to fly or walk about that world, exploring mountains or forests, and choosing a scene to render to an image. The software eventually became a commercial release called
MojoWorld, which went through three releases to end with version 3.1.1. ==Cinema work==
