	Within a given production, sometimes a large number of actors and singers and dancers are on stage, and sometimes there are only one or two.   What if the theatre could adapt dynamically? When the whole ensemble is performing, the purple seating sections could be pushed back, leaving a large stage (top diagram).  Then when they all exit and we're left with a soliloquy or a duet, on cue the purple sections could move in to closely surround a small hexagonal performance area (bottom diagram).
