This shot is part of the ending scene and was generated using my GeoGL
library, which is a simple library for drawing and managing objects in
3D space. The image in the corner is slightly later in the demo, and is
the only use I've ever had for 1D textures. :) The source code for
GeoGL and to our demo are available at
