the barber pole illusion extra post

The image you see below is the barber pole illusion.  The barber pole illusion, is a barber pole that’s rotating along the long axis, but the diagonal stripes appear to move along the pole in a fashion which is inconsistent with the actual direction that the pole is turning. The barber pole illusion also demonstrates how motion is perceived through first-order perception, which only sees movement as continual. The feature-tracking aspect of second-order perception does not perceive the aftereffects of a motion; it perceives movement as stroboscopic, or as a series of still images
