BANDALOOP: Dancing on a Skyscraper

BANDALOOP is an aerial dance company that combines choreography and climbing technology. This video was recorded as part of a grand opening for a 17-story commercial building, with six dancers suspended from individual ropes.

The effect of the building’s windows adds a great touch to this performance, as the mirror effect seems to double the number of participants (and also provides a counter-motion to each performer).

Found via MetaFilter, with several more links in the original post.
