Do you see the dancer turning clockwise or anti-clockwise?
This is good for hours of entertainment:
Right Brain vs Left Brain test
After a bit of practice I can see her turning either way, by closing my eye for a moment and thinking of the direction I want her to turn.
I don’t know about this test. Unless I misunderstand how they are orienting things, I can only see the dancer turning clockwise. Yet, I’m very strongly left-brain dominant.
