Motion illusions are visual phenomena where static images appear to be in motion. These illusions occur due to the way our brains process visual information, often relying on patterns, colors, and shapes that trick our perception. For example, the Rotating Snakes illusion creates the impression of swirling motion, even though the image itself is still. These illusions can be influenced by factors such as contrast, brightness, and surrounding elements. They highlight the complexities of human vision and how our brains interpret visual stimuli. Understanding motion illusions can provide insights into the workings of the visual system and the nature of perception.
