THADGAVIN is a collaborative work between Thaddaeus Frogley and Gavin
Buttimore. They were one of the winners of the 2001 I.O.C.C.C
(International Obfuscated C Code Contest - http://www.ioccc.org ) with
"Most Portable Output". This competition rewards those that write the
most obscure C program. The goal is to show the importance of
programming style, in an ironic way, and to illustrate some of the
subtleties of the C language. I.O.C.C.C and THADGAVIN in particular seem
to us creative and interesting for another context like art.
