Left brain or right brain
Click on the above link and see, then come back here and tell ME (because I am curious). When I saw the image in miniature I saw it as clockwise, bigger I saw it as anticlockwise. I don't know what it means that I now see her swing from side to side. I tend to identify more with the right brain traits, though I think I actually have a big logical streak in me too - maths and science were never my strong points however. If you slide your eyes away from her to the left or right she seems to change direction.
Now my eyes are all hurty.
