From Shamus Young ( A screensaver for Windows which generates and performs a fly-through of a nighttime cityscape.

   * There are no art assets. All content is generated at runtime.
   * Aimed at older graphics hardware. The goal is for the program to perform acceptably on machines "five years old or less".
