Obfuscated C Contest Winner
This actual flight simulator program, although extremely cute, is a maintenance programmer's nightmare. Consider it as an extreme example of completely unformatted source code. (The authors of this program are aerojockey.com; you need the X11 libraries and must read the directions at their web site if you really want to compile and run this).
