The Art Project powered by Google features interior tours of seventeen world famous art museums.
Select a museum from the list on the homepage and you can virtually tour it using the same interface style you experience in Google Maps Streetview. Inside the museum just double click to zoom to a location. You can also open a floor plan overview and click on a room to navigate to that part of the museum.
You pass through the long security line at the United States Capitol building in Washington, DC. While the line of tourists streams forward into the Exhibition Hall, you turn right, and head to the Senate appointment desk. There, you sign in, get an ID badge, and are guided by a security officer to a large meeting room.
