The Calder Foundation and the University of Virginia have announced a policy change in response to an unusual protest about a scuplture. When the university installed "Tripes," a masterpiece by Alexander Calder, on the campus, a sign was posting barring photographs of the work, which is on loan from the foundation. Students took to Facebook, suggesting that the policy be protested by having as many people as possible shoot photos of the work -- and students responded, as seen in this photograph from The Cavalier Daily. The university responded with a clarification: While the Calder Foundation bars photography of the sculpture for commercial purposes, students are free to take as many pictures as they would like for their own personal use.
