WorldWind rocks. Think of our globe, in full hardware-accellerated 3D, mapped with all the satellite pictures NASA can get ahold of. WITH terrain elevation. AND country, city, and even landmark names. Add latitude and logitude, animated tracking of global events, and up to 1 meter pixel resolution via the USGS (United States Geological Survey) data, and you have an absolute winner.
Oh, it's completely free, too.

...My house is at latitude 31.73548 by longitude 35.19559. Drop on by anytime.
