Do you see the lady dancer turning clockwise or counterclockwise?
With focus you can change the direction. Can you do it?

If clockwise, then you use more of the right side of the brain;
if counterclockwise, then the left. Most would see the dancer
turning counterclockwise.

I've always known I'm left-brained so I was confounded when at initial
glance I saw the girl spinning clockwise. It took me a while and a few
epileptic upward eyerolling and peripheral gazes to switch directions
and ultimately assert that primary servitude indeed stems from the
left brain.

Under the right brain column, only items number 3 and 15 typify the
deranged me.
