Google Earth, Now With Oceans and Mars

Google Earth is at once really cool, and really creepy. Seeing my house from space (and noticing that my car was in the driveway) makes me feel a bit watched. However, we showed the kids the top of one of favorite restaurants, and they recognized it from the parking lot. And, we also use it to see faraway places, like family's houses in Japan.

The newest addition to Google Earth are the oceans. That's really cool. But also - why? If you can think of something, here's a free version of Google Earth, Oceans (and Mars) included.
