This is easy. Look, and see which way it appears to you. For me, it's usualy counter-clockwise at first.
But then focus on the leg sticking out. If you see her going counterclockwise, then her sticking-outleg is her left leg.
If you see her going clockwise, it's her right leg.

Wierd. The only way I could see her go counter clockwise was by hiding the left and middle one, watching the right, then adding the middle one back in. Even then, if i hid the right one, it was a struggle to keep seeing her spin counter clockwise. Watching her go counter clockwise just felt unnatural.
