Besides working at the Portland Spirit, I have finally sent off the drawings for Arabian Nights. Here’s a sample. 
Nouranihar cart
The idea is that we have a two part cart that can be wheeled on and off as one unit, but can also split and expand. The pieces for Scene 1of Nouranihar slip in between the pieces for Scene 2, using tracks much the same way we did for the mockup of Abu Al Hassan.
I think the first two layers of Scene 1 would not need to be in tracks, because they would not have Scene 2 pieces directly behind them. (See elevation drawing for idea on how the individual scenic elements would be constructed.)
