The yellow arrows pointing to the left or green arrows pointing to the right? There is no correct answer. Different people see different arrows at first<img src="http://de.acidcow.com/pics/20101102/25_great_optical_12.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />A  "false spiral" - actually a series of concentric circles, hard as it may be to believe. To prove that there's no spiral, try tracing your finger around one of the circles. You'll see that it never moves inward or outward.<img src="http://de.acidcow.com/pics/20101102/25_great_optical_13.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />First, look at the image at a close distance, then look at it from 1 meter distance<img src="http://de.acidcow.com/pics/20101102/25_great_optical_15.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Hover you mouse cursor over the picture.
