Find The Curved Line

About

Find The Curved Line refers to an optical illusion showing a 7X7 checkerboard pattern of what is presented as straight green lines over a gray, TV static-like pattern that appears to consist of curved lines to the naked eye. An image macro using the image captioned "go ahead, find the curved line" became popular online in early December 2021 challenging viewers to find out which line is actually curved.
