If you haven't been over to UGO.com today, check it out -- they've done a complete site redesign and it's pretty nifty. Also, if you scroll down on the main page, down in the right-hand column, you'll see a nice little HeroMachine plug that'll change every week to feature one of the recent contest winners.
The UGO front page is prime digital real estate, and from now on if your character design wins the bi-weekly contest, your work will be shown to millions of visitors!
