Looking to waste some serious time? Look no further, and head on over to Google GlobeTrotter. GGT is not a Google site, but a site that catalogues available satellite imagery of things like buildings, alien spaceports, and really cool images that just happened to be captured by the satellite. Have a gander, it’s a great idea, and a cool way to get a peek at a bunch of places and things you wouldn’t normally see, or think of looking for.
