Imagine yourself in a racing car, driving along the streets of Seattle (or San Francisco) and seeing all the real life street pictures. Navigate using keyboard of a mouse, just like you are playing Need for Speed, but instead of a game, you are seeing real pictures of the streets in Sea or SF. Ok if you cannot imagine then Don't. Head over to

http://preview.local.live.com and try it yourself. All in the browser (and for the Fox fans, it works in FF as well)
