Australian graphic designer Cameron Booth has sketched out the U.S Numbered Highway System as if it were the London Tube. "Stylistically, the map definitely borrows from the London Underground 'Tube' map, although the final look is somewhat different due to the complexity of my map," Booth wrote by email. The map's detail only gets the justice it deserves in the high-resolution version available on Booth's Flickr account. (via)
