I think it switches on it's own.

This reminds me of a sign that was outside this gas station I worked at when I was 18. It was essentially two signs meeting to form a right angle. Depending on how you looked at it, it either looked like it was pointing away from you or toward you. It was a neat optical illusion.

I wonder if the people who can see the dancer spinning both ways at will have better cognitive abilities. Maybe if someone creates a whole set of optical illusions like these we can "train" ourselves to think in different ways more easily.
