The Detroit Institute of Arts' Tango-powered augmented reality tour looks fascinating

Visitors of the Detroit Institute of Arts can head to the front desk and ask for the smartphone before embarking on the AR tour. Viewing the exhibits through the Phab 2's display presents another layer of reality invisible to the naked eye. For example, you can see the mummy's skeleton, visualize the Ishtar Gate at scale, and see the written characters and figurative scenes inside the Mesopotamian seals. It's all rather clever and makes for a much better use of a smartphone in the museum instead of, you know, landing selfies with the mummy or something.
