Round circles optical illusion


The pattern made by the black and the white boxes is that of four round nested circles. They are NOT arranged in a spiral.

  1. I hate to disillusion you, but those are squares.

  3. Technically, they are rectangles. Their squareness would have to be verified. True squares have to meet stringent requirements.

  4. Interestingly, if you stand back some distance (will vary) it's no longer an optical illusion. They look exactly as they are drawn--non-touching concentric circles.
