I did it! I made her turn counter-clockwise !!!!

Basically, try doing those three things at the same time and you should be able to see her moving counter-clockwise:
1. stare (and I mean STARE) at her feet, not her body;
2. very quickly blink your eyes, observing the direction of movement after each 10 or so blinks;
3. force the fact, that she's supposed to move counter-clockwise, into your head.
If you get over the first barrier (getting her to move in the other direction for the first time), it's actually rather easy later on.
