Repurposed maps

As you may (or may not) know, I have a little fetish with information graphics. Mapping, and maps, fall into this category. I love the shapes of cities, the spaces between spaces, roads and such...it's all about patterning for me. So you can imagine my delight on finding some decor tips about how you use map and repurpose old maps to make something new. I can't remember where I found all of these, I think a google search will suffice.
