Got a call from our set designer - she's going to be adjusting the big unit and making it a little smaller, taking a little off each side. This very large unit sits all the way upstage and is white, and includes several doors that do different sorts of things, and some panels that swivel. The set for whatever scene is projected onto it - she's been using two projectors with a Cinerama-like "join" line in the middle. It's been problematic, so she's going to one projector and that won't fill the entirety of the unit, so she's taking some off the sides.
