In the latest news about your phone being smarter than you, Google Maps now offers a service that allows you to navigate museum floor plans. Dozens of museums and libraries--30 in the U.S. alone--have signed on, according to The New York Times. Shopping malls and airports are also participating in the service.

A few of the spaces that you can fake walk through are the Museum of Natural History in New York, the Art Institute in Chicago and the Freer Gallery in Washington, D.C. A full list is here.
