Illusions

In this amazing optical illusion, if you stare at the blinking pink dots, you will see only one color; pink. If you look at the the + in the center, you will see a circle of pink dots and a rotating green dot. Now, stare at the + without moving your eyes.

Are the centre dots the same size? Check out below

Look at the black dot in the middle and move your head (and upper body, if it's attached) forwards and backwards (you see, not only is this a piece of optical spookiness, it's also a cardio-vascular workout).

Do you think block A and block B have the same color? Look at the answer below and be amazed!
