Yep--i can make her go any way I want, as long as I make the choice while only looking at her peripherally. If I'm looking directly at her, she stays spinning the same direction until I look away.
In the process of looking at this thread (scrolling down and then back up) it changed for me.
For me, I concentrate on her arms, because I think they're the key to the illusion. If you can force yourself to see them going the 'wrong' way, it might help.
