Hey, Gracie ... I saw a similar (but way more expensive) set-up a couple of months ago in a friend's home near the Woodland Hills area of Los Angeles .... but it was four screens across and three screens high.
Each individual screen had an almost negligible boarder which made the distracting lines almost invisible and the video geeks were adjusting the program that broadcasts different parts of the overall TV image to each individual screen.
And some audio-geeks were busy setting up a very complicated BOSE sound system with speakers surrounding the room and something that appeared to be a huge pipe shaped boom box partially hidden in a darkened recess of the 12 foot ceiling.
And then another tech crew came in with leather lounges each complete with sound systems of their own and once each lounge was set up, it would move/vibrate in conjunction with whatever was shown on the screen.
Later that week I watched a small part of THE PACIFIC on this unreal home movie theater .... a scene in which the Marines landed on a hostile beach and it was amazing because I was sitting in one of those chairs that responded to what was on the screen and I felt like I was getting blown up just like it was real.
And on a couple of occasions, I actually ducked when it sounded like machine gum bullets were being fired inches over my head.
I guarantee ya that this type of set up will be standard home entertainment equipment within the next few years.
Next visit is AVATAR in BlueRay and 3D, but they say that FOOTBALL is a real nerve wrack'n experience.
Now I gotta find a real theater pop-corn machine and offer it as a thank you gift.
