I encountered a collection of fans in a physical therapy facility. The fans are suspended from the ceiling by very long rods, possibly as long as ten feet. I was first struck by the fact that the fans are rock-stable. There is no visible wobble at all. I have no idea who manufactured them.
Observed from the floor, the fan blades move counter-clockwise. I noticed, however, that if I told myself the blades were moving clockwise, I could actually see them that way. Take a look yourself and see if this little mental trick works for you.
