For an ageing dinosaur, NASA sometimes does some cool stuff

My mate Henry downloaded one of the coolest web applications I've ever seen the other day. World Wind is a program produced by NASA that gives you access to maps of the entire planet. What's so cool about it is that the maps are images taken from NASA satellites and you can basically zoom in on any part of the globe, in some places with a resolution of about 1 metre! You can pretty much zoom in so far that you can make out cars driving on the streets of some cities! The maps can also be viewed in 3D so you can see what the landscape looks like. This is the coolest geek toy ever - you can basically check out the scenery anywhere on the planet...
