Google Cartography: Street Art in Your Neighborhood is a curious google hack by Richard Jones:
Google Cartography uses Google via the Google Search API [] to build a visual representation of the interconnectivity of streets in an area.This application takes a starting street and finds streets that intersect with it. Traversing the streets in a breadth-first manner, the application discovers more and more intersections, eventually producing a graph that shows the interconnectivity of streets flowing from the starting street.
Figures and show maps generated for two of the world's great cities, New York and Melbourne, respectively.
Why do I blog this? because I am fascinated by interconnectivity.
