The spirals are actually there, partially concealed by plain circles, so seeing spirals is not really incorrect. Your visual system is good at seeing concealed things. That's why I disagree with it being classified as an illusion. Though not as much as with the Kanizsa triangle.
- dwringer 9y ago"The spirals are actually there" - the unbroken spiral is not there, and it is an illusion of one, not multiple. At least to me. I guess if you want to be particular, the circles are broken by the pixels on my monitor, but at 4k that isn't perceptible. I guess if one gets far enough away from the monitor that one can no longer resolve the space between the circles it could be said that the spiral is actually there.
