Regular readers of this here blog may wonder why I've linked so many times to maps of the London Underground. I've always loved the clean design of Harry Beck's 1933 map because it looks so much like a circuit diagram and conveys complex three-dimensional information so clearly in 2D.
The London Transport Museum has put together a cool map that contrasts the original 1933 version with the 2004 iteration—and then with the real street grid.
Gosh, I does love the Internets!
