I recently stumbled upon this inverted version of Google Earth. It's called wikisky (although I thought I read that as whiskey.) If you like constellations or astronomy, this is a beautiful site to check out.
I know absolutely nothing about stars and constellations, etc. But they sure are pretty.
I also like this site because I live in an extremely well-lit city. And I can't remember the last time I saw the night sky.
