Download Google Earth
Did you ever want to explore shipwrecks such as the great Titanic? Well, now you'll be able to do it from your computer. The latest version of Google Earth offers you that and more, like a pretty cool view to the ocean and the sky. If you get tired of earth, you can easily switch to Mars and take a close look. It is compatible with Windows XP, 7 and Vista. There's only inconvenient to it, that the program may use a large cosume of RAM so if you have an older machine you might experience a little bit of trouble, other than that there is only one thing more: you will love it.
