Women Dancing on the Women's Building

MM reader Andy Miller was walking down 18th Street last Thursday when he spotted a group of women dancing on–wait for it–the Women’s Building.  Soooooo meta!  I especially like the part where one of the dancers braces herself on a pole protruding from the roof while performing some sort of aerial cycling maneuver.

Unfortunately, Andy couldn’t figure out exactly what was going on, but he did manage to shoot some great video.  Anyone have any ideas?
