Are You a Left or Right Brain Thinker?

Yesterday we got this crazy discussion as to which direction the image is moving. I see it going clock wise while two persons I know see this image go counter clockwise. How about you? Are a left-brain or right-brain thinker? That is an amzing test ... I can only see the image moving counter clockwise if I take time and really concentrate looking at it... but by default? I really see the image moving clockwise.. How about you?

See further explanation about it...
