The online T-shirt store Threadless started off March with a BioShock shirt design contest, and although most of the submissions so far are fan art of the game that's not even out yet, the rules only demand that designs are based on the "descent into rapture" theme.

Some shirts take advantage of the translucent twilight tide atmosphere in the game, but others are just outrageous art that only a few might obsess over. Seeing Jack Sparrow wrestle a squid is funny, but I'd never buy something like that. The shirt that gives the big daddy enemy vision was clever, but a little sloppy, and the 'dead sucker' shirt is really polished, but a little morbid. What's your favorite one so far?

The contest ends on April 1st, so if you don't like what you see then try entering a design of your own. You're allowed to enter three different shirt designs, but good luck beating my BioShocker shirt idea seen above. Just gotta vector art that bad boy and hope some sick freak doesn't own the rights to the shocker symbol. Here's the prizes to get you motivated:

A brand spankin' new Xbox 360 premum system
A full year of Xbox Live Gold
BioShock for Xbox 360 and PC
BioShock Xbox 360 faceplate
1-year 12 Club subscription
$300 Threadless Gift Certificate
$1,500 in cash

Hmm, Destructoid submarine perhaps? Dtoid robot scuba divers? Ron Workman drowning a clown? Just a suggestion, I'll do anything to tide me over until this game finally comes out on August 21st in America (August 24th in Europe). Thanks to reader Fana7ic for the tip of the awesome art entries, and let us know if any of you decide to bring change the them to robotic rapture with some Dtoid fan art.
