Fantastic! I literally bought some primed 1x2.5in boards for the frame and spray painted black. With the projection properly fit within the frame it literally just looks like a gigantic TV. I feel the screen looks better than any bar projection screen I've seen. I can't believe how much more you can see. It's an amazing experience.
Yes, we could certainly do something like that. Our closest standard size is this one: http://www.amazon.com/Carls-Blackout-Cloth-16-Projector/dp/B007KA7BAA/
Check that out and give us a call or e-mail if you have any other questions.
This will work outside. I would suggest just hanging it tree to tree or with a large scale stand. However cleaning has been one frustrating part. I got a spot on mine and when I cleaned it it smeared and never faded any. I just leaned to get used to it.
