Check out this fun Moving Mona Illusion. The image of the Mona Lisa is overlaid with a version of an Ouchi Illusion to create the perception of movement in the Mona Lisa’s face. If you don’t see it, try focusing on the face and moving your head to the side. Please note that this one doesn’t work for everyone.

What is the Moving Mona Illusion?
The Moving Mona Illusion uses the Ouchi Illusion to create the perception of movement.
The Ouchi Illusion, also known as the “Rotating-Tilted Disk Illusion,” was indeed created by Japanese engineer Hajime Ouchi in 1977. The illusion involves a floating disk that appears to rotate and tilt in an unexpected manner when viewed from certain angles.
Here’s a description of the Ouchi Illusion that is used in the Moving Mona Illusion:
- Setup: The illusion features a white disk that appears to float on a black background. The disk is adorned with black patterns, usually in the form of radial lines or concentric circles.
- Perception of Rotation: When you view the disk from certain angles, it appears to rotate slowly, almost as if it is spinning on its own axis. However, if you try to focus on a specific point on the disk, the rotation seems to become erratic and difficult to predict.
- Perception of Tilt: Additionally, when viewed from different angles, the disk appears to tilt or incline in various directions, making it seem as though it is not lying flat.
- Floating Illusion: The most captivating aspect of the Ouchi Illusion is that the disk seems to float independently of any physical support, adding to the puzzling effect.
The Ouchi Illusion is a remarkable example of how our brain’s visual system can be easily deceived by simple patterns and the lack of visual cues. The rotation and tilt perceptions arise from the interaction between the disk’s pattern and our visual system’s tendency to interpret motion and orientation based on the surrounding context.
This illusion has been studied and admired for its elegant design and mesmerizing effects. It serves as a testament to the complexity of human perception and how easily our brains can be tricked into perceiving something that doesn’t exist in reality.
How Does the Moving Mona Illusion Work?
The Moving Mona Illusion uses the Ouchi Illusion to create the perception of movement.
The Ouchi Illusion, also known as the “Rotating-Tilted Disk Illusion,” is a fascinating visual illusion that tricks our brain into perceiving motion and tilt in a stationary disk. The illusion works due to a combination of factors related to our visual perception. This is how it works in the Moving Mona Illusion.
- Contrast and Pattern: The disk used in the illusion is typically white with black patterns, such as radial lines or concentric circles. The high contrast between the white disk and black patterns enhances the illusion’s effect.
- Pattern Gradients: The black patterns on the disk are carefully designed to create gradients in the thickness and spacing of the lines or circles. These gradients are essential to producing the rotating and tilting perceptions.
- Lack of Depth Cues: The disk appears to float on a black background, which provides little to no depth cues. Without any surrounding visual context or cues of depth, our brain struggles to accurately determine the disk’s orientation and motion.
- Eye Movements and Fixation: When viewing the disk, our eyes naturally make small, involuntary movements called microsaccades. These eye movements, combined with our brain’s attempt to stabilize the visual input, contribute to the illusion of motion.
- Peripheral Vision and Peripheral Drift: The disk’s patterns stimulate the peripheral vision, which is more sensitive to motion and changes in patterns. The black patterns create the illusion of peripheral drift, where they appear to move even though the disk is stationary.
- Ambiguous Rotational Cues: The specific arrangement and gradients of the patterns create ambiguous rotational cues that make it challenging for our brain to determine the true rotation direction.
All these factors work together to create the Ouchi Illusion used in the Moving Mona Illusion. When we view the disk, the lack of depth cues and the stimulating patterns cause our brain to interpret the disk’s orientation and motion in unusual ways. The disk appears to rotate and tilt, even though it remains static.
The Ouchi Illusion and the Moving Mona Illusion are compelling examples of how our brain’s visual system can be easily deceived by certain visual patterns and lack of depth cues. It demonstrates the complexity of human perception and how our brain relies on contextual information to interpret the visual world around us.
Some Similar Illusions
The Moving Mona Illusion uses the Ouchi Illusion to create the perception of movement.
There are several visual illusions similar to the Ouchi Illusion used in the Moving Mona Illusion that play with our perception of motion, rotation, and orientation. Here are some examples of similar illusions:
- Rotating Snakes Illusion: This illusion features a pattern of overlapping circles and lines that appear to rotate continuously, even though the image itself is static. It creates the perception of motion and rotation in the image.
- Motion Aftereffect (Waterfall Illusion): This illusion occurs after staring at a moving pattern for an extended period and then looking at a stationary scene. The stationary scene appears to move in the opposite direction to the original motion, creating the sensation that the world is flowing in the opposite direction.
- Rotating-Tilting Cylinder Illusion: This illusion involves a three-dimensional cylinder with horizontal stripes that seem to rotate and tilt when viewed from different angles.
- Enigma Illusion: This illusion features a series of concentric circles with a radial pattern that appears to rotate when viewed, creating the illusion of motion.
- Leaning Tower Illusion: This illusion involves a picture of a tower that appears to lean or incline depending on the arrangement of surrounding objects.
- Spinning Dancer Illusion: This illusion features a silhouette of a dancing figure that can be perceived as spinning clockwise or counterclockwise, depending on the observer’s perspective.
- Pulfrich Effect: This illusion occurs when viewing a moving object with one eye covered, causing the object to appear to move in a curved or slanted path.
- Fraser Spiral Illusion: This illusion features a spiral pattern that appears to grow larger as it moves outward, even though it is a continuous shape.
- Kanizsa Triangle (Illusory Contours): This illusion involves the perception of an invisible triangle when three Pac-Man-like shapes are arranged to face inward. Our brain fills in the missing information to create the illusion of a triangle.
- Hering Illusion: This illusion features two straight lines that appear to bow outward when surrounded by radiating lines, giving the impression of a barrel shape.
These illusions, like the Ouchi Illusion and the Moving Mona Illusion, showcase the fascinating complexities of human perception and how our brains can be deceived by certain visual patterns, gradients, and lack of contextual cues. They continue to captivate and intrigue researchers and enthusiasts in the field of psychology and neuroscience.
