Valve have sent through word they'll be running a music video contest for Portal 2 where budding young creative types are charged with creating a music video for the end credits track from Portal 2, "Exile Vilify", by The National.
Starting today and running until midnight July 15th, the contest asks the community to make a music video for the song "Exile Vilify" using whatever visuals they choose. Once aspiring video directors have completed their work, they may submit their videos on YouTube using the tag PORTAL2NATIONALEXILE. After the deadline, Valve, The National, and the community will select the winner who will win a prize package including a guitar autographed by The National plus a collection of Portal 2 merchandise.
Obviously "using whatever visuals they choose" is an option to be taken in reason, and this is YouTube we're talking about, but it's also the internet. If you decide to enter, be sure to also share your video with us in the Comments section or on our Forums.
