Have you seen Google Earth?

Everytime I think Google has out-done themselves with another neat new technology. I'm still impressed with Google Maps (and the Satellite view!) and Picasa. With Google's purchase of Keyhole's image library and technology, they have been able to add neat imaging services to their offerings. Now comes Google Earth! I'm stuck. I'm addicted. I have got to stop playing with this and get some work done! And the best part is the basic services are all free. Awesome quality images from satellite.
