Take you to travel around the United States in a sports car.

This service from Microsoft Live is quite interesting http://preview.local.live.com/. The map is divided into two parts, the top part shows real-life images while the bottom part shows the map. There's a nice car on the top section, and you can direct the car to go anywhere, while the top section displays the real image of the destination. It's very interesting, as long as your internet speed is fast enough, the top part of the image is dynamically displayed, just like real life. You have three options to choose from: Walk, Race car, Sport car. Below is a screenshot:
