In 1987 Eric Graham was the person who made the Juggler demo for the Amiga. For the demo he developed a ray tracer program named ssg, what later would evolve into Sculpt3D. The original source code of Raytracer was never found, but the web page dottyflowers.com has now found one of the original disks with the source code of Raytracer.
