Clint,
The fluorescent light behind the screen causes the shadow at the back. My first test was done with the screen mounted in the living room; I also projected on to the screen too. There was no indication of shadow then. When I first attached paper to find the correct bonding point I did get some screen distortion but I put that down to the tape being stretched a little as I applied it then shrinking back again. I used double-sided tape for the one in the video and was more careful on how I applied it. So far no distortion has occurred on the one in the video. The bond is effectively holding a maximum weight of 5 grams per centimetre but that is assuming it has to hold all the masking cloth. In reality, the cloth is mostly held by friction as it lies on the roll of screen. The only time the bond has to hold the full weight of the cloth is during the transition from going around the screen roll to being rolled up with the screen.
