Geez. Thanks for giving me another distraction, Linky.
I love maps. I once had a collection of all of the maps that came with the National Geographic (not all of the maps, just the ones from my subscription, duh). And one of the coolest things on the Return of the King DVD is the interactive map of Middle Earth, where you can follow along the paths of the Fellowship and click and see scenes from the movie.
