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.
LEFT BRAIN FUNCTIONS uses logic, detail oriented, facts rule, words and language, present and past, math and science, can comprehend, knowing, acknowledges, order/pattern perception knows object name, reality based, forms strategies, practical and safe.
RIGHT BRAIN FUNCTIONS uses feeling, "big picture" oriented, imagination rules, symbols and images, present and future, philosophy & religion, can "get it" (i.e. meaning), believes, appreciates, spatial perception, knows object function, fantasy based, presents possibilities, impetuous, risk taking
*All I can see is right/clockwise, but Wes saw both.
