A fascinating and really well done interactive music video from The Arcade Fire, all done without Flash. I don't think there is anything else like this on the web right now.
Put in the address of your childhood home or some other location and the video seamlessly cuts footage of that location into the video. And you guys thought Goole driving around destroying everybody's privacy with their Street View cars was a waste of time.
Note: Requires that you are using Chrome or Safari or the beta of Firefox 4. If you're running IE, then you're most likely SOL.
For the web-nerds among us: more details on all the elements that make up the film.
