I wasn't really sure where to post this but I have always enjoyed GFX Battles.
It's basically where two GFX Artists challenge each other to who can make the best graphic with a certain stipulation. Say... the top be make a Obie Trice Album Cover, everyone involved makes one and all the other members vote for the best one, usually its the first person to get 3 or 5 votes.
What do you think about this idea because I wouldn't mind challenging other GFXers to battles.
