Yep, now Google Earth can show you the sky! It'll show you a view of the sky right over your current position (or any you pick), then you can navigate around just like you do on the surface view. It'll animate the view, show constellations, time lapse... amazing for you budding astronomers, or folks who want to practice with celestial navigation. At free, the cost is right too!
By the way, if you haven't tried out Google Earth, you should. Amazing technology that lets you "fly" anywhere in the world and look at satellite photos of locations. Check out your house! I can actually see my boat in the marina, although the picture was taken about 5 years ago.
