My da-lite model b should be here in a few days. It occur to me that if it can be installed upside down (the screen would pull up instead of down) the case could be hidden behind furniture. I would put a hook (or two) on the wall to hold the screen. Does anyone know if this is feasible? Does the recoil spring mechanism would work in this position? I could install it either way but if done in this manner it can be completely hidden when not in use.
