Google Earth™ displays satellite images of most inhabited regions of Earth, allowing users to visually see things like houses and cars from a bird’s eye view. The degree of resolution available is based somewhat on the points of interest, but most land (except for some islands) is covered in at least 15 meters of resolution. Its a great fun tool to have when your bored you can try find your house, take a sight seeing trip around the globe or use the hidden flight simulator
(Press Ctrl+Alt+A) for a quick fly around, it only includes two planes the F-16 Falcon and the Cirrus SR-22 not a very good simulator but as you can imagine the scenery is great.
Also included is Google Sky™. This is a fun tool for looking out into the stars with major constellations and other points of interest shown in very high detail and after clicking you are provided with some information about the object.
A recommended download for anyone with some spare time. Download from here.
For some reason mine crashed after I started spinning the globe around really fast and letting it go. Maybe it exceeded 1670km/h (the rotation speed of earth at the equator) and the people on it started getting nauseas.
