The beautiful building dancing (video below) is by Project Bandaloop, a San Francisco-based dance company founded by Amelia Rudolph. Their repertoire includes natural landmarks such as Yosemite as well as very tall buildings around the world.

Their new show, Boundless was premiered in San Francisco in September 2011 and included parts of the dance, Caprice which is filmed below and which was first shown at Orange County Center.
