Instead of concentrating on her chest, concentrate on the woman's movement. If you see her spinning clockwise, that means you're using the right side, or more creative side of your brain.

Focus on her shadow, and try to imagine her spinning in the opposite direction. Alternatively, tilt your head down and look at her out of the top of your eyes, and try to imagine her spinning in the opposite direction. Sooner or later she'll switch for you.

Our brains are trained to overlook the word OF.

If you saw all 6 Fs right away, you're a genius.

Most people see only 3 Fs. Some people see 4.

Look at the chart above and say the COLOR of the word, not the word itself.

Why is it so difficult? Because the right half of your brain is trying to say the color, while the left side of your brain is trying to say the word.

An island, right?

Turn it upside down, and you'll see what it really is: a crater.
