Can we add in retractable?
I've been trying (unsuccessfully it seems) to add "retractable" to the UST + ALR combo. I'd like to deal with side lighted environment to install a TV replacement in a family room. I definitely want this to be retractable so that when we're not watching, I can hide the screen.
I just recently found Carl's site and it looks like his material can be used in this scenario, but a) its the only UST/ALR/Retractable combo i've found and b) i'm not sure how i feel about building my own. Any alternatives or pre-built options? Also would be great to get something better than 40deg viewing angle...
