When I first saw this picture I was wondering why there was that paint smudge in the middle of the ceiling. That's an awesome library. I was watching some show a few months back that showed a bunch of houses that had secret rooms. They followed a company around as they showed some of there work from the simple stuff. To big projects that used magnets on chess pieces that when moved in a certain way opened the door. You said you did all the work yourself Gris?
