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).

This is the result of using SD's CFormatter tool on the Obfuscated C contest winner. A programmer might actually be able to work on this version.
