Artist and scientist Stephen Von Worley's detailed and ambitious project Crayon the Grids uses color to show the orientation of streets in major metro areas. The images are beautiful as well as visually informative. Thus far, Von Worley has created maps of Paris, London, Berlin, Tokyo, New York City, Washington, D.C., Boston, Chicago, San Francisco and Los Angeles.
