Gary Whitta wrote in with his proposed moratorium: the wall of expository newspaper clippings. They’re a movie staple, but I’ve never seen one of these in real life.

Part of the difference may literally be the framing. Newspaper clippings pinned to the wall reads as crazy/obsessive. Clippings nicely mounted and hung reads simply as pride.
