Scenic Automation

Absolute Motion Control supplied two lifts and a large friction drive truck, controlled by their new Desk[Three], with three playbacks. The automated structures were built by Weld-Fab. [information from Instagram @theatreautomation]
The set design is gloriously efficient and brings the action downstage (under the orchestra, who float above the stage) in a variety of configurations seamlessly.
