Fucking hell, that completely and instantly worked. I looked at the first object in the room, determined to come up with something interesting about it- the corner of three planes in the wall, over by the foyer, which makes a 3d platform about 7 feet off the ground. Instantly I was thinking about its structure and what it concealed and what was on top of it. I would not have been thusly inspired to think about that wall had I not set out to see it that way. Nice.
