Went a little crazy for my birthday this month. Spent the weekend completely redoing my living room and adding a slightly bigger screen than my 52" LCD.
1) Mounted the 52" TV to the brick wall on the opposite side of my living room
2) Mounted an electric 120" screen to my ceiling for event and evening theater viewing...it is AWESOME
Everything is completely automated. I have a 4x2 HMDI switcher which runs the signal from my 360, Mac Mini, Tivo, or PS3 into the projector and 52" LCD simultaneously. I hit one button on my Harmony One and the TV turns off, the screen drops, the projo turns on, the receiver switches IO and the appropriate AV device is activated. I've wanted something like this since I was 10 years old....and now it's mine...I RULE 😎
