One of the reasons that I love looking at ceilings is the shift in perspective. We spend so much time looking down, only a little time looking forward or around and almost no time looking up. It expands the mind when you force it to see the same room from a new angle.
Some person of vision at El Huffington Post (the Spanish language edition) has taken underwater photos of Olympic synchronized swimmers and flipped them 180 degrees so that it looks like the swimmers are standing on the surface of the water.
