Google Earth

I only read about the incredible GoogleEarth program after donating to the public my tongue-in-cheek invention (filming the earth from an airplane, etc.) GoogleEarth is not as good as the BetelnutSpyPlane screen installed in your local bar would be, but it's cheaper. Actually, it's one of the coolest things I've seen. The quality, alas, is quite a bit higher for the U.S. than for, say, Taiwan. You can still see plenty, though. I've been playing around with it for hours - an incredible teaching tool, too!
