One of the most fascinating things about optical illusions is their ability to trick our brains into making static images appear to move, shapes distort, and colors change. From the famous Müller-Lyer illusion to mesmerizing spinning circles, optical illusions come in many forms, each showcasing the extraordinary complexity of human vision.

Whether through blurred figures, perspective distortions or geometric patterns, optical illusions continue to fascinate researchers and enthusiasts, revealing the mysteries of perception and cognition.
