If you are in tune with the world then you probably have herd about the google maps. I have spent hours scanning the earth from above. Its the voyeuristic feeling I experience that keeps me going back for more. But now google has done it again and just introduced google earth. You should definitely check it out while it is free its features far surpass those of the google maps. The only downfall, it only works for PC's at the moment but you can count on google releasing a version for the mac in the near future.
