Synchronous Objects is a super interesting collaboration between choreographer William Forsythe and Ohio State University's Advanced Computing Center for the Arts and Design. It is a series of projects is to explore the art of dance from a scientific and data visualization perspective.
One of the sub projects, entitled Cued Annotations, visualizes a dance where each of the dancers starts their part upon a specific cue from one of their fellow dancers. You can watch the dancers preform the dance from a front or above stage view, and then re-watch the choreography with all the cues and their effects annotated. The project creators were "interested in the intensity and integrity of the dancers' attention to one another, the rapid exchange of information, and the different qualities of motion in each cue response". I can't wait to see more
