I'm stumped! I want to guess that props or set pieces appear between the ride vehicle and the screen, but this could cause projection issues. I'm trying to balance the fact that the ride uses screens, like Simpsons, but requires a ride track and travels throughout that enormous show building. So somehow, FJ uses both "hemispherical" screens and live-action props and sets. Would they use blackouts to transition between the two, like they (sort-of) do in Poseidon's Fury when the walls raise and lower?
I personally enjoy the riddles, ScottInNY -- and I actually think it adds to your credibility. Any joker can pretend to have inside information from their "source" and just spill it in one post. It's hard to make crap up in riddle format, unless you're a REAL jerk. (See how I made you feel either really good or really bad?)
