A trip around the world

I know that everyone knows Google Maps. But do you know how addictive it can be? I have spent hours just cruising around our Earth, checking out some beautiful satellite images from different locations. You can see Niagara falls, Mumbai's slum area, Amazon rainforests... and it actually helps a little if you have a huge travel fever! (And one of these screenshots is from the place where I'm going to be in a couple of weeks!)
