I have a unique mounting situation for a new customer. I am wondering if any of you have ever mounted TV's in or on the ceiling with the screens facing the floor? If so, what method's/produts have you used? This is for a local dentist, who was visiting a dentist in another city when he looked up and saw a TV hanging horizontally on the ceiling, so patients can see it whil lying on their backs. I've seen smaller ones this way, but never a 20". Any suggestions would be helpful!

Thanks
