In addition to Arcade Fire's The Suburbs, they have released an interactive film,The Wilderness Downtown.It's an experiment using Google Chrome (download here) and HTML 5. You enter the address to where you grew up. "We Used to Wait." starts playing with a young boy running down the street, multiple windows with video start popping up, moving around with the music, and you're transported back to your childhood home. It's a truly amazing interactive experience.
