I am trying figure out a way to make walls fall towards the audience so that they can become decking and reveal scenery behind them. I was initially thinking of using counterweights and a pulley system underneath the platforms. I may also be helpful to note that this at an outdoor theatre and there is no fly system and I start construction on a bare stage. I usually use 1/4 inch ply to face the walls and 3/4 inch ply for the decking. I could go on with more details, but I am hoping for any advice at all.
