 SelfGOL was written to win all four categories in the Obfuscated Perl contest (3rd year, I believe, whose web pages are no longer available) and still comply with other restrictions of not using modules and being under 1000 bytes. Alas, the rules were drastically changed for the following year's contest, and so it was never entered.
