From the hallway, this appears to be the busiest door in the department: Rebecca Moore Howard's office. Here I find newspaper clippings, an inspirational poster on achievement, cartoons, a flimsy whiteboard with "Survival 101" at the top. And another blue flier for Spring '06 courses. It covers another poster. The space of the door's surface is scarce, but layering opens the space onto another dimension; layering produces a third space. One on top of the next, a cake: The Evening Sun, an LGBT Studies poster, and a New Yorker cover peeking through. How much depth can a door accumulate before it exceeds the limits (as strictly defined by a building code for hallway hazards)?
