Teleport around the globe with this excellent Google mashup (via @DanBowen)
I can see this working as a lesson starter for creative writing or in geography (obviously). Probably lots of other ways to use it too. It's great fun.
It is good fun, but if I were to use it in a science lesson say, what kind of animals live in this habitat, I'd spend 15 mins teleporting until I found somewhere decent. You would have to be quite lucky to get somewhere which isn't some generic street with fly-tipping and doubleparking.
