Parkour

Traversal in flight. The art of moving across (usually urban) landscapes, parkour is similar to some martial arts systems in that it comes packaged in an insistence on a particular way of living and seeing: you're a traceur 100% of the time. Acquisition of skills is more about functional progression than tricks. Like breakdance, parkour is a separate artform that's informed circus heavily, and that's got a certain caché and underground (but not too underground) popularity that's become very attractive to programmers and commissioners.
