No, Cabspotting is not a new website devoted to getting a cab to your door within seconds (but holler at me when you find that one). It's a little more ethereal than that: Based in San Francisco, from the Exploratorium, Cabspotting uses Cab Tracker to follow and trace the path of 10 SF yellow cabs. The diagram looks like an otherworldly arterial system, rather than just a Google Map, and it's hauntingly beautiful, whether you happen to live here or not.

The Exploratorium has invited people to create art and projects utilizing Cabspotting, so don't miss the work put up online — I love any Internet art galleries I can get my mouse on.
