The Brick Wall Optical Illusion first went viral in 2016 after being posted to Facebook by Arron Bevin, challenging users to find what was wrong with the image. At first glance, it appears to be a standard brick wall with a small stone or gap, but it actually features a cigar wedged horizontally between the bricks. The meme gained massive traction because once the human brain perceives the cigar, it becomes impossible to revert to seeing just the wall. It is frequently used to represent 'red pill' moments, hidden truths, or the frustration of trying to explain a complex realization to someone else who hasn't 'seen it' yet.
