And what are you guys talking about?

I'm talking about the spinning silhouette illusion on page 202.
Depending on which direction you see the silhouette going you can, sort of, determine which brain hemisphere you mainly use.
Usually left-hand people see it spinning clockwise, but I am right-handed so things are obviously more complex. I found a description on youtube that summarizes the characteristics of each brain hemisphere.
"If clockwise, then you use more of the right side of the brain and vice versa. Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.
