Which brings me to the next question/problem: How exactly should I build that frame? And won't it look awkward? How can I make it look cool? Should I paint the 'box' black, or match it to my wall (beige)?
NOTE: I have no room for any sort of curtain to put around the screen. It will be right up to the ceiling (well, the left half will be), and I have about 5 inches on either side of the frame. There just happens to be an electrical outlet in the upper left corner of the wall. Perhaps I could put some sort of "rope light" around the left, bottom & right sided for ambient lighting... I'm not so sure I like that idea, though.
Any other thoughts?
