He’s got the whole world in his hands
Well, it’s not quite Google Earth, but earthscape.com has a pretty feature complete demo of a 3D globe running on the iPhone complete with tilt navigation and that pinchy zoomy goodness we all paid the big bucks for. Of course, Google Earth on the iPhone is pretty much a party trick, as who the hell needs the ability to zoom around the earth while waiting in line at Dunkin Donuts? (Oh, excuse me, STARBUCKS. I forgot it was the iPhone we were talking about for second).
If only I could go back in time and show that to Columbus. Now that would be a fun thing to do with the iPhone.
