Choreographers Seth Riskin and Mia Keinanen have developed a new form of dance. “When I am onstage, I’m not really being a gymnast, and I’m not really being a dancer, either. I have no dance training. I am a light dancer, which is something different. It’s not just the movement of the body, it’s the movement of the space as well, since the light defines all of the space around me.” Boston Herald
