As a trainer, I love this one - which is more important - a ceiling fan to keep the students cool and awake so that can learn - or a projector?
It reminds me of beck in the day we had our classroom renovated. They installed a really nice projection screen with a dry erase board behind it. This was really expensive because it was fairly new and was wired to a switch in the wall. The first class, one of my fellow instructors wrote on the screen with a marker, claiming that he didn't realize that the screen was down. What a dumbass. Even though it was dry erase, it didn't really come out of the screen material and it was ruined on it's first day.
