These illusions are created as a byproduct of the brain’s attempts to make sense of thoroughly confusing inputs. As the mind focuses on different details, its conclusions about what it sees can change and adapt—and this morphing interpretation introduces a sense of motion and sometimes even unease in the viewer. Some motion-effect illusions will seem to change right before your eyes and others will appear to rise off the page, even though you know this is impossible. Interestingly, each person's ability to unravel the illusion differs—so there will be some that fool you more easily than others, and you’ll find your favorites may not really impress your nearest and dearest. In some cases, you may have trouble "seeing" the solution even after you know precisely what is going on. Are you ready for some mind-bending motion-effect illusions?
