Is this dancer spinning left or right? This is even crazier than the dress!

Forget the dress!

Is this dancer spinning clockwise or counter-clockwise?

Counter-clockwise, right?

At least that's what I thought at first, but when I looked a second time, she was spinning clockwise.

It all comes down to whether you think she's spinning on her right foot or her left foot. Called a kinetic, bistable optical illusion, this example was created in 2003 by web designer Nobuyuki Kayahara per Wikipedia.
