What action takes place in the window? Other versions of these games had some cool thing that would happen or something would move.
Based on what I have seen from other windows used for the Sorcerer game, there will be a video projected on the large open spot on the back wall. I am still not sure how they are able to project video so well onto a surface with a pattern on it, but it works. You can also see the two boxes that have holes in them for the cameras that focus on the players.
