Robin Canup has difficulty keeping her hands still. On her computer monitor, a cosmic ballet is being played out before her eyes. There is no sound, but you can easily imagine music accompanying the dance. One minute it is subdued and serene, like an ethereal violin, and then it is dynamic and dramatic, with a lot of brass and percussion. Two dancers fall into each other’s arms and a shower of sparks explode into surrounding space. Glowing fragments trace graceful paths across the three-dimensional stage, under the strict choreography of the force of gravity. Some of them merge to form a new ballerina, and the performance ends with an intimate pas de deux. Robin sits transfixed to the screen as the drama unfolds, her shoulders and wrists swaying slightly back and forth in the heavenly breeze, as though her slender body wishes to join in the dance.
