Research and scientists have several theories about how our eyes and mind collaborate to create an illusion of movement—although the precise neural mechanics remain unknown. Is the visual picture a prank? No, the vibrating rosette combines several illusory effects. When you fixate on a pattern, it momentarily remains on our retina as an after-image. It is technical, but eye movements cause a ghost image to overlap with the actual image on the page—called a moiré effect: similar, repetitive patterns merged together at slightly different angles, creating a rippling effect. Got that? By adding two high-contrasting colors, blue and yellow to the picture the effect is enhanced. When you approach an object, our brain normally makes adjustments so that the object’s size and brightness appear to remain constant. But when you move your head back and forth, the alternating dark and light patterns in the rosette change in both size and brightness. Magic—no? Our visual system cannot bring the blurred boundaries within the image to focus, and the brain cannot adjust. Fuzzy thinking or fuzzy seeing? Does it hold true when reading? Absolutely. Different people take away different things from a book.
It is rare indeed to find a person who takes time to think clearly. Too often our fast-pitched, over-stimulated, jacked-up society acts like a school of Piranhas responding to something falling into the river rather than rational people created in the image and likeness of God. Apply what the Bible says to your life. You cannot go wrong. There is good reason to think clearly. Read 2 Peter 3rd chapter for clear and “wholesome thinking”.
Now, take another look at this rosette. Seeing is believing—except when the mind can be tricked into believing what it sees. Clearly, here is what you need to know:
“Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.” Philippians 4:8
