http://www.fakeisthenewreal.org/ (fakeisthenewreal.org) is full of great maps. For example, the above pictures are to-scale drawings of subway systems in New York, London, and Madrid respectively. More cities can be found at their "world subways":http://www.fakeisthenewreal.org/subway/ page. I like it when people reorganize information and maps in new ways. Other cool cartographic remixes found on fakeisthenewreal are "Chicago Mile by Mile":http://www.fakeisthenewreal.org/milexmile/ in which one picture representing every square mile of famously grid-like Chicago is shown on the city map, and "Public Schools in Order":http://www.fakeisthenewreal.org/ps/ (shown below) in which all of New York's public schools are connected in numerical order.
