I probably should explain what this is, for those who don't already know. If you use Microsoft Maps live there is a "BIRDS EYE" option, which allows you to see an area as if you were flying over it. It's not the same as an aerial view. It's much closer, and it allows you to rotate to see areas from alternative angles. This option is available for many major cities.
