Is it only me, or do these circles composed of black and white squares, seem to cross-over? You be the judge! It worked for me… Amazing. Similar one here. I’m still not sure how these illusions work, and boy, we had many of them here in the past. Another version would be the one, where the concentric circles seem to make a spiral. Be sure to check more of these in seemingly bent category. Mind can be though to deceive, but that isn’t the case with this website. Enjoy and don’t go delusional!
