Regular readers of this blog will know that both Chet and I are enthusiasts of the sky simulation program Starry Night. This program allows you bring up on your computer screen any view in the sky at any angle.
But what about an Earth simulator?
This week Google released "Google Earth" -- a simulator which uses satellite images and 3D modeling to recreate any view on the planet Earth. You'll need a fairly decent Windows PC to run it (No OS X version yet - boo hiss!) but you can't beat the price. It's free!
As a demonstration of some of the fun you can have with this software, I put together a little geography quiz for you. See how many of these landmarks you can identify. Click on the thumbnail views for a larger image.
The last one is a view perhaps only Chet will be familiar with. :-)
