+/* This program was originally written to be single-buffered: it kept
+ building up new objects in the front buffer by never clearing the
+ depth or color buffers at the end of each frame. In that way, it
+ was drawing a very small number of polygons per frame. However,
+ modern systems make it difficult to live in a single-buffered world
+ like that. So I changed it to re-generate the scene at every
+ frame, which makes it vastly less efficient, but also, makes it
+ work right on modern hardware. It generates the entire system up
+ front, putting each "frame" of the animation into its own display
+ list; then it draws successively more of those display lists each
+ time the redisplay method is called. When it reaches the end,
+ it regenerates a new system and re-populates the existing display
+ lists. -- jwz.
