I was looking around the room during a meeting the other day, and noticed a bizarre looking mask (some kind of tribal art, I think) hanging at what seemed like an unusual height on the wall. Upon further inspection, it was revealed to be covering the thermostat.
It was also obscuring a small sign describing the effect that raising or lowering the thermostat would have on the other rooms in the suite.
"Ahh," I thought to myself, "Pure genius. What a perfect example of designing the environment to support the desired outcome."
