About This Illusion
This illusion is particularly interesting. There is a pink circle surrounded by concentric pink and purple rings. If you focus on the pink circle, the rings appear to spin or scintillate, as if there were some activity in them. Of course, nothing is actually moving.
Try This
- Focus on the pink circle in the center for a while.
