Jim Andrews's teleporter has a simple interface. You begin in the control room of the TARDIS (naturally). Click on the teleport button to go somewhere on Earth. You'll promptly see the nearest photo in Google's archive.
Andrews calls himself a "programmer-poet," so this device is a work of art. It's also a way to explore the world, albeit not in any particular order. His inspiration for the project was a game in which people are shown panoramic photos from around the world and are then invited to guess the locations. You can do the same thing with the teleporter. Just click on the Map button to see the location of each photo.
Dress in layers. You may end up in a hot desert or in the Antarctic interior.
