Do you have a projector mounted in your ceiling? Or are you thinking about it?
Take a look at where your media source - DVD, PC, cable box, Tivo etc - is located. Chances are the collection of assorted boxes are located somewhere in front of your sofa.The ultimate location for the projector on the other hand is usually somewhere above you.
