I love google earth. You can get some amazing pictures, even of the farm in Lusaka, as you can see from earlier posts on this blog.
If you haven't seen it, and you can get a really good broadband internet connection, check out Google Maps Street View, and incredible way to explore the world from your armchair. It hasn't come to Toronto yet, or the UK but covers a lot of mainland Europe, Australia (including Melbourne, Mwamba) and the US.
I can't wait for sea floor views from Google Ocean, yes it really is coming!
