They did an amazing job of making you feel like you were in the boy's head. Most of the "scenery" was lighting or projections. Very cleverly put together to show the boundaries that existed in the mind. There was nothing walling him in except for the perception he was walled in.... Or not. They also did a fantastic job of getting the audience to perceive what it was like to panic and freak out within that brain and how much control it took to overcome such an episode. Four of us went, two old, very jaded, critical stagehands (JC and I) Donald and M. All four of us thought it was a great show.
