I have seen this on lots of spots so I thought I'd make one here..
Basically, you have to make icons after I give you the topic like, Edward in the cafeteria, Edward with Bella.. You don't HAVE to make them yourself but I think it's more original if you do!!!
Every few days I'll pick the best one and you get 3 points for 1st place, 2 for 2nd, 1 for 3rd.. ;) then I'll post the new topic.

ROUND 1) Edward in the meadow (pick in progress)
ROUND 2) Edward in the cafeteria (open)
