Isn't this why a few groups are working on iphone coding apps? :p
I had a teacher in elementary who didn't like her students staring at the ceiling while she taught. Thinking that we were trying to escape from the lesson, she put several famous paintings (Mona Lisa, Sistine Chapel, etc) on the ceiling so we would at least be learning to appreciate art while in her classroom. There was nowhere in the room to look which wasn't educational.
