Hyposurface wall!

Not exactly what I had in mind but the fact that electronically controlled pistons can manipulate the surface of this wall is pertinent to my precedent research. I think theater and auditorium designers would love to have the ability to manipulate the surfaces along the ceiling, floors, and walls to accommodate for a specific type of performance. Maybe one could even use the technology to create openings in the envelope in the building, synergy-zing the interior and exterior environments, creating a whole new space for performances and lectures.
