Here's one for random articles mostly centered around norway.
I converted it from a plugin for World Wind so I won't take any credit for it (even if I used 3 hours on it :P ).

There has to be a way to get a complete list of geo references in Wikipedia though. imagine how cool it would be to have this many articles all over the world.

if anyone comes across a way let us know. converting it to KML is easy enough.
