This is In Orbit, an art installation and performance piece by Ward Shelley and Alex Schweder. The two collaborate in a medium that they call "performance architecture." In this case, it's a wooden wheel that measures 25 feet high. In Orbit is currently located at The Boiler, a gallery in New York City.
There are beds, chairs, desks and some kind of toilet in the structure. Shelley is in the exterior and Schweder is in the interior. The two men are living there for 10 days. They are currently in the middle of their performance, which lasts until March 9.
Both of them have to live separately, but in harmony. In order for one man to go to one part of the house, he must have the cooperation of the other.
