The 'Find The Curved Line' meme is based on a famous optical illusion where a series of intersecting gray lines on a white background create the sensation of curves in the viewer's peripheral vision. Despite the visual trickery, every line in the image is actually straight. The image became a viral sensation as a 'find the curve' challenge, eventually morphing into a relatable meme template. It is typically used to represent the futile search for something non-existent, such as looking for motivation, logic in a chaotic situation, or a hidden meaning where there is none. Its popularity stems from the universal experience of being deceived by one's own eyes.
