Ideally, this would be mounted on a vehicle, so it could easily be moved. I would like to see it ornate, in the traditional sense, with Comedy/Tragedy masks, and perhaps saying "All the world's a stage" across the top. It would be even cooler to see a vehicle with a set of theatre seats that could be trailered around with it, and people dressed as ushers. Perhaps even a mobile popcorn stand.
I shall see how realizable this idea actually is. I can see there being issues with having a large flat, tall, sail-like structure on wheels, although since it is mostly empty hole, it may not be too much of a problem.
