wither in the light

Google Earth is now live. This is the result of Google's acquisition of Keyhole, which was the coolest world-mapping software I'd ever seen. It's like a digital globe you can spin around and zoom in on, and you can bookmark places, overlay the maps with information (I saw a French city that had an overlay of a map of that city in the 12th century), and share your findings with others.

There's a free version, and a couple of commercial versions with more options. They got hit pretty hard on the initial release news, so the downloads are disabled right now, but it should be available again in the next day or two.
