Keyhole is brilliant for bored afternoons.. essentially allows you to view satellite images from mainly the US.. the forum has people who picks up on weird and wonderful places.. like aeroplanes flying in the air or a highway that goes right through a mountain. I went to Vatican City and finally realised how close it was to Rome (I never knew). Here's something strange.. possibly some kind of anchor rig.. but from far it looks like the world's largest jellyfish, if you compare it to the ships.
