My first idiot thought was “this is what dancing in zero gravity will look like.” Then I actually put some thought into it and realized “no, it won’t.” Not even a little bit. The majority of the moves here are reaction-driven… airflow pushing differentially on the body due to the aerodynamic configuration of the moment. In zero-g, this sort of airflow would promptly cause the subject to get sucked into the fan inlet or blown out the hole into space; if there’s no or minimal airflow, the dancer might still make the moves, but there’ll be little in the way of actually spinning and tumbling, and none in the way of swooping around. To make that happen a dancer would have to be equipped with some form of reaction control system. *Possibly * (but unwisely) done with compressed gas jets at the hands and feet; the environmental control system would have to compress the atmosphere just as fast as the dancer releases thrust-gas, or else the environment will begin to overpressurize. Another solution would be to have fan-based thrusters at hands and feet. Maybe a backpack turbocompressor. Any case would doubtless be noisy as hell. Power consumption for the fans, reaction mass consumption for the cold gas system would all be quite high. Substantial risk of banging into stuff or losing control and spinning dangerously fast. Those are all very good points. But, consider this: the dancer would get to fly around like Iron Man.
