Google street view Google sky map I've been playing around with these two and they are pretty cool. Street view has an option to turn on compass mode and as you move the phone around it will turn the view to match the direction you are facing -makes it feel like you are really standing in that spot looking around. You use the stock map app but get in real close to where you can click on a business or address and then you get the menu that has the street view option. Then turn on compass mode. With sky map, you aim your phone up at the sky and it shows you the different constellations and stars. You can pick an object to look for, like say, mars, and the phone will point you to its location.
