When we first moved in, there was a seminar room that made some people physically nauseous due to its sloping walls. For a time, they were trying to use masking tape on the walls to make the effect less pronounced. Some of the grad students tried to name it the "vomitorium", but the name never stuck. Fortunately,, once the room had a full compliment of chairs, furniture, and a projector screen the effect seemed to be much less pronounced.
