Flashmob at TedxSF
On June 4th, students and alumni of the San Francisco Conservatory of Dance participated in a flashmob-style performance during the introduction of "ALIVE! Maximum Living as a Human," the fifth big TEDxSF gathering at Yerba Buena Center for the Arts. This wonderful event was orchestrated and choreographed by Eli Nelson.
