I imagine brightness (darkness) control will be the final nail in the coffin of my plans for HT in the loft. The area is open on two sides to big triangular windows so the whole house would have to be blacked out in order to get a dark viewing area...

... or maybe I could borrow from Get Smart and come up with a "cone of darkness" which could be lowered for movies
