The only time I've had a reaction to a screen is in Niagara Falls at this indoor ride where you get strapped into these seats in a dark room and on screen you are on a rollercoast and it shows the camera in the POV of someone sitting at the front.. craziness. And there was a dinosaur hunting part where our truck got nudged off a cliff and it really felt like we were falling... good times.
Are you talking about the Volcanozor 3D? lol the only 3d ride we have here in Montreal and they haven't changed it for almost a decade.
As for the demo.... installed and primed!
