Anyone build a false wall and covered with spandex floor to ceiling?
I'm contemplating a new DIY AT screen and rather than build an actual 136" screen to hang on the wall, I'm wondering about building a full size false wall that I will cover with white over black spandex, floor to ceiling, wall to wall with all speakers and equipment behind this wall, virtually hiding everything. My idea is to completely hide the idea that there is a screen at all, appearing as just a normal wall (made of spandex for AT properties) that comes to life when the image is projected.
I know that the material would need to be seamed, but this could be done with horizontal seams running the full length below and above the screen image height so that the seam would not interfere with the picture.
Anyone done this or seen it done?
Bad idea? I know I'd need to get a projector with excellent blacks and contrast since masking would be very difficult.
