A few weeks ago, I took down the plastic insulation from my front window. I had been pleased that it had lasted so long (5 years), because it was difficult to install, since the window is so large. Recently, though appearing smooth, the plastic started casting strange textural patterns on the wall. But it got a bit trashy looking from the outside, and it occurred to me one day that the unexplained texture/shadow thing might be some cancer-causing property, and maybe I was being off-gassed slowly to death. So off it came, in just minutes, and the result is quite dramatic (brighter!), even if this particular photo doesn't show it.
