I've been to that haunted house its just a black maze with one scene where they take your picture of you getting scared... a car comes out of the wall with lights and a horn and it takes a photo. The photo system costs around $30,000 I know because we just got back from New York where we worked on a haunt in Time Square that will be the same thing just a black maze with a photo system. Eventually they are turning the haunt into a world class attraction but this is what they wanted to do just for Halloween.
Apparently the system makes a lot of money... we are hooking up the camera next week so I can report back on how it works. Larry
