What is the Green Checkerboard Illusion?
The Green Checkerboard Illusion is a version of the Checkerboard Bulge Illusion.
The Checkerboard Bulge Illusion, like the Green Checkerboard Illusion is a visual illusion that involves the perception of apparent motion in a static image.
The illusion consists of a checkerboard pattern drawn on a flat surface, and when viewed from a particular angle, it appears as though a 3D shape is rotating or bulging outwards. However, in reality, the surface is completely flat.
The key to the illusion lies in the arrangement and orientation of the black and white squares on the checkerboard pattern. Sugihara cleverly manipulates the depth cues in the image to trick the brain into perceiving depth and motion.
The Checkerboard Bulge Illusion demonstrates how our brain interprets visual information and relies on depth cues to construct our perception of the world. Even though the image is static, the brain interprets it as a dynamic 3D object, leading to the illusion of motion and bulging.
The Green Checkerboard Illusion is not only fascinating but also has practical applications in computer graphics, animation, and robotics, as it helps researchers and developers understand how visual perception works and how to create more realistic 3D representations in digital environments.
How Does the Green Checkerboard Illusion Work?
The Green Checkerboard Illusion is a version of the Checkerboard Bulge Illusion.
The Green Checkerboard Illusion works by exploiting our brain’s natural tendency to interpret visual cues and depth perception. Here’s how it works:
- Checkerboard Pattern: The illusion starts with a regular checkerboard pattern with alternating black and white squares. This pattern provides a regular grid that serves as a reference for our brain to perceive depth.
- Perspective: The image is designed in such a way that when viewed from a specific angle, the black and white squares create an optical illusion of a 3D object rotating or bulging outwards. This perspective is crucial to the illusion’s success.
- Depth Cues: Our brain uses various depth cues to interpret the world in three dimensions. In the checkerboard bulge illusion, some of the critical depth cues at play are:a. Gradient of Size: The squares are arranged so that the size of the black and white squares appears to change gradually from one side to the other. This gradient suggests a change in depth, and our brain interprets it as a bulging or rotating shape.b. Perspective Lines: The diagonal lines formed by the black and white squares converge towards a vanishing point. This convergence simulates a sense of depth, contributing to the illusion of a 3D object.c. Shading and Lighting: The illusion includes subtle shading and lighting effects that further enhance the perception of depth and 3D form.
- Ambiguity: The checkerboard bulge illusion relies on visual ambiguity, meaning that our brain is presented with conflicting visual information. Our brain tries to reconcile these conflicting cues and ultimately perceives the image as a 3D object.
When we view the checkerboard bulge illusion from the appropriate angle, our brain combines these depth cues in a way that makes the image appear as if it is rotating or bulging outwards. However, if we change the viewing angle, the illusion may disappear or change, highlighting the importance of the specific perspective for the Green Checkerboard Illusion effect.
Some Similar Illusions

There are several other optical illusions that are similar to the Green Checkerboard Illusion, as they also exploit our brain’s depth perception and visual processing. Some of these illusions include:
- Rubin’s Vase: This illusion depicts a vase in the center, but there is also a silhouette of two faces facing each other in the negative space on either side of the vase. Depending on how you perceive the image, you may see either the vase or the faces, but not both simultaneously.
- The Necker Cube: This is a classic 3D illusion that involves a cube drawn with lines on a flat 2D surface. When you view the cube, it appears to change orientation spontaneously, flipping between two possible 3D interpretations.
- The Penrose Triangle: Also known as the “Impossible Triangle,” this illusion depicts a 2D drawing of a triangle that appears to be a 3D object, but its structure is impossible in reality.
- The Ames Room: This is a real-life optical illusion room that uses distorted geometry to create the illusion that people of different sizes can appear to change height and shape as they move within the room.
- Motion Aftereffect (Waterfall Illusion): This illusion occurs when you view a moving pattern or object for an extended period and then look at a stationary scene, causing the stationary scene to appear to move in the opposite direction.
- The Hollow Face Illusion: This illusion involves a concave face mask that appears convex when rotated, fooling our brain’s depth perception.
- The Ponzo Illusion: In this illusion, two identical lines appear to be different lengths because of the context of converging lines in the background.
- The Floating Finger Illusion: When you look at your finger held close to your face with one eye closed and then switch eyes, your finger appears to shift sideways due to the change in perspective.
These illusions, like the Green Checkerboard Illusion, demonstrate the fascinating ways in which our brain processes visual information and creates our perception of the world around us. They challenge our understanding of reality and highlight the complexity of human visual perception.
