add latitude and longitude data to every place in the online encyclopedia. This is pretty cool, as it allows you to check out a Wikipedia article and jump straight to a Google Maps satellite view or punch the place into your GPS unit. But wouldn't it be cooler if you could do the opposite, i.e. look at a map and see all the associated Wikipedia articles? You know where I'm going with this--Wikipedia for Google Earth. One clever soul has taken a snapshot of the geocoordinates Wikipedia makes available and put them together as a .KMZ file that you can load into Google Earth. There are tens of thousands of coordinate pairs in the nearly 2MB XML file, but they're all logically separated into layers since seeing them all at once is a tad overwhelming. It's available in both English and German, and uses Google Earth's built-in web browser to display the Wikipedia article when you click on a placemark. Very cool.
