Sheril KirshenbaumDo you see a series of sunken rectangles or 16 circles?
This is The Coffer Illusion.
Our brains are geared toward identifying objects & here, “pixels” are grouped to form edges & contours, shapes, & objects. The image is inherently ambiguous so there is no “right” grouping.
Rectangles dominate first for most people - including me, but keep staring & the image may flip to circles.
