A "Lit Trip" is a digital tour of the places and settings in a work of literature - think of it like a mashup of Google Maps and your favorite novel! Lit trips can combine images, text, multimedia, and background information concerning a work of literature, and it can put these elements in their geographically-appropriate places. Imagine seeing background context for The Odyssey superimposed over a map of the hero's travels, or following along with the Joads as they travel west from Oklahoma to California.
The Google Lit Trips site contains Google Earth based lit trip downloads, divided into age-appropriate groups for children and adults.
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! :)
