"This comprehensive virtual tour allows visitors using a desktop computer (Windows, Mac, Linux) or a mobile device (iPhone, iPad, Android) to take a virtual, self-guided, room-by-room walking tour of the whole museum. You can even browse a list of past exhibits, which is included on the ground floor map (see upper right map buttons). The visitor can navigate from room to room by clicking map locations or by following blue arrow links on the floor that connect the rooms. The desktop version includes camera icons to indicate hotspots where the visitor can get a close-up view of a particular object or exhibit panel. "
