A couple of days ago i downloaded Google Earth and i wasn't impressed with it but now i am! Google Earth is a program which gives you satellite pictures of everywhere in the globe. The reason I wasnt impressed with it at first, was because where I lived - it wasn't a good satellite picture. But... When I went away on holiday in Majorca and came back I went on Google Earth and where I was staying It was really clear! I had another look at other cities and found out that capital city's are very clear! I also had a look at this country with a volcano (forgotten the country now! ) and you could actually see it really clear - you could even see little rocks in it. If you would like to get it - heres the link - Click
