Street View in Google Maps

Now, Google Maps gives you a new way to explore the virtual maps: street level view. Currently in Denver, Las Vegas, Miami, New York, and San Francisco, you'll find a button that says "Street View". Once you click on that button, watch the street marked with blue lines and click on one of them to see a street view for that location. To navigate along the street, click on the white arrows or use the arrow keys. You can also rotate the image and see a complete a panoramic view.
If you thought that the textual instructions aren't descriptive enough, Google has a made a video and uploaded it to YouTube:

The product is expected to raised concerns over privacy and personal security as it could actually capture the face of individuals. Currently, you could report individual streets you find invading your privacy by clicking on the 'Street View Help' link. This is how you can get caught when you are trying to have fun outside your office ;)
