New York artist Alex Schweder talks about his latest piece of performance art, living inside a giant hamster wheel.
Ward Shelley and Schweder will be living inside the wheel for 10 days to illustrate people's interdependence.
The 25-foot-tall wood and steel structure is equipped with everything the duo need from beds, a kitchen and a toilet.
The two men must co-ordinate their movements while rotating the wheel, or risk being thrown off.
