Art captures constant motion of Asian Megacities

Megacities - cities where over 10 million people live - are on the rise, and nowhere more so than Asia. The impact of such growth is felt on both residents and the environment.

Now 11 artists, including Ai Weiwei, are capturing those changes and constant motion by using everything from bicycles to plastic bags. Their works are on display at a new exhibit in Boston's Museum of Fine Arts.

Produced by Sarah McHaney. Edited by Bill McKenna. Filmed by Ian Cartwright.
