Around the world in a minute

I've discovered the most impressive piece of software I have seen in a very very long time - it's called Keyhole, and allows the user to zoom into anywhere on Earth from space, sometimes at such a high resolution as to allow for views of individual houses and cars. I found my old house in London!

It's very addictive to use - I've been using Keyhole to track the course I'll be following next year, and the video you can see here shows the entire route (1.82 MB Quicktime Movie) in one minute!
