Map of Public Art in Chicago

Those cool folks at the Chicago Public Art Group have an awesome "Public Art Map" that allows people to view and learn about public art installations all over the city: sculptures, mosaics, installations - they've got a lot of entries all on one handy Google map.  (In fact, they've done such a great job populating the map with public art examples that you'll probably need to zoom in to a specific neighborhood to be able to see everything!  :)
