Christo, the world renowned artist, has created massive and controversial public art works, including wrapping the German parliament in fabric, the 24-mile-long artwork called Running Fence in California, and The Gates in Central Park. He talks about his newest projects: Over the River, in which he plans to cover nearly 7 miles of the Arkansas River in Colorado, which has sparked lawsuits by local groups, and Mastaba, a pyramid-like structure built from oil barrels that will stand in Abu Dhabi, his first permanent structure. He talks about the meaning of his art and his lifelong partnership in art and life with his late wife Jeanne-Claude, who died in 2009.
