Analysis: The programming aspects of home and breakup deserve separate attention.
home
home actually includes two pieces of code. home.pov, the POV-Ray source, is a design document. The problems it solves are (1) how to represent telescope and signal source (2) how to arrange the pieces so they are all visible (3) how to impliment the clock variable so the pieces change in a coordinated fashion. anim.cpp solves the more general problem of animation in POV-Ray: how to call the povray program, which only renders a single image, enough times to generate an animation. Numbering needs special attention since UNIX thinks that 10 comes before 2 (and it does--alphabetically!).
breakup
From milky and explorer, the basic framework for an OpenGL program was well established. The new challenge in breakup was to coordinate the interaction between the console and the graphics display. Also, some scheme for representing the relative "size" of a data packet was necessary. The frequency-time space was chosen because those variables are actually used when determining the size.
