The Trippiest Optical Illusions on the 'Net

There is the ISIS, called ‘The most difficult puzzle ever.’ It sure has put many minds and brains to test, but here is something that’ll put the two halves of your brain confronting head-on for supremacy? Asking your witty bit to decide which half of it was more dominating, helping you figure out things – and did you always figure them out correctly.

It is the test of the Right brain with the Left brain, and it’s time to concentrate, not on the lady, but her movement, that’s gonna decide the rest. If you see her moving clockwise, then you’re using the creative side of your brain, that is Right. Whereas, if you see her move anti-clockwise, then you’re using the logical part of your brain, that is the Left.
My first impression of the dancer was that it is moving anti-clockwise, and that’s how most of you would see it too. However, if you try and focus, who knows you may see it move clockwise, if you do plz let us know also.

I see both. But it takes me some time to switch from one to another. Cover the upper body and focus, then you'll see counter-clockwise. Cover the bottom half and focus to see clockwise again. At least this is how it works for me.
