I really want this. They're releasing a soundtrack bundle and this is part of it. They're only released what the poster will look in the dark which is another thing that Disney are doing. They release material bits at a time to keep the interest of the fans/audience.
Also, the mini site they've made for the movie is fantastic. it has so many easter eggs, it keeps in theme with computer terminology. There's a light cycle game too which is bloody great too. Just shows how much effort they're putting into the viral marketing of this film. Can't bloody wait.
