Wind Games. It's a beautiful meld of dance and gymnastic-style athleticism. My sole regret is that the safety helmet makes it impossible to see the performer's face.
I love new art forms and particularly new art forms that are enabled by technology (see for example Bandaloop). In one sense there's nothing tremendously new about performing dance moves and poses in three dimensions - dancers have been leaping and spinning for centuries. In another sense, this style integrates the technology in ways that I don't think would be possible otherwise; just look at how much of the time the performer spends head-down for example.
