I had a proposal I did once for this idea..... Covered patio, Clients wanted a screen that would face the pool. They actually had the perfect set up. I would install the screen in the soffit and speced a Da-Lite tensioned motorized screen with the rear projection screen material and a projector and lift. I was going to build a completely weatherproof box that was climate controlled ( the air vent was right behind where i was going to build this) and have the lift go into that. I also was going to add rain and wind sensors just incase and program that into the system.

However the deal feel through because the client lost his job...I am still hoping he calls me when he gets back on his "feet"

However I never thought of the bugs....completely slipped my mind
