Very well done, but the concept gets a bit boring after the first dozen or so pages. The image from outside is projected into the room, upside down, through a window using a "pinhole camera." So you get room after room, maybe a conference room with a picture of the city on the wall, or a bedroom with the brick building across the street. The photographer is obviously very talented, I just didn't think the concept was strong enough to carry an entire book. Glad I got this from the library and didn't use a credit. Plus it is huge, it would have probably cost more than four dollars for someone to mail.
