Techotic

Look at the picture of a ballerina spinning below, if you see her spinning anti-clockwise then you’re using your right brain and if she’s spinning clockwise then you’re using the left brain.

This is not a trick picture, but it’s your brain that’s playing trick on you. Basically, the picture is a 2D image, the rotation occurs in the 3rd dimension, your brain tries to view the picture as a 3D object spinning, thus, if you want to change the direction of the spinning simply place your finger below the ballerina and spin your finger in the opposite direction for a few seconds.
