Murdy showed a screenshot of one of his scripts at Midsummer recently. Someone should snag a screenshot from one of the livestreams!
To be specific, it looked like one page that was a first person account of what was happening to them in the maze and what they saw. Then, there was an additional companion page that then broke down that page into all the elements (set, sound, lighting, props, scareactors, etc) and said specficially (jn a non POV matter) of how to pull off that scene. I think that's actually a very interesting way to tackle it.
Orlando had a completely way to do it, with a little map of the room and such on the side.
