I stumbled on this one-- http://www.youtube.com/watch?
and placed it on full screen and watched it all the way through. It's sort of a review of how Google maps were made and moves it all the way up to what they are doing on it now, how much of the earth has been mapped and improvements to it such as 3-D. Thought some of you might want to see it. Do so when you have time to set & enjoy all to the end !!!
