Illusion Optical Visions

Optical illusions and brain games in the ability of the eyes to capture moving images.
These different perspectives are captured in such a way by the brain, which seems to be an image in movements.

Instructions:

TECHNIQUE ONE: look at the image without focusing the view anywhere. After a while, you begin to "feel" that something happens. The image will begin to move, when you notice that this happens, stay relaxed and continue doing the same.
Your eyes will do the rest of the work.

TECHNIQUE DOS: Put a few centimeters of the image. Let your eyes get used to seeing the image from close up.
Then without allowing the focus to move slowly until you reach a length of your arms stretched from your eyes to the image, relax and you will get to see it, if you do not repeat it again.
