This came to my attention today!

Other than the gratitude of the team that is running the logo contest -- if you win -- you get a shirt with your logo on it. Also, these guys also seem to have access to a CNC machine, so they are also offering you a wooded engraved version of the logo for your desk!
check out their site for more information on who and what they do!
