A recent Apple Hot News article looks at Troika Ranch, a New York City-based digital dance theater company, who deliver “stunning live performances that unite dance, theater and interactive digital media.” They do it with the help of Macs and MidiDancer, a wireless sensory system that attaches to a dancer’s costume and triggers visual and musical accompaniment. “When Troika Ranch performs, sensory devices worn on each dancer?s body link the performer’s actions to interactively controlled video, sound and light. A bending arm can warp a video image, the kick of a leg can recall a musical phrase.”
