An optical illusion I stumbled upon when working on a project. All squares align perfectly to the same grid, but appear slightly misaligned (to me at least). ☛ Click the pattern to switch to the next version (there are 24 in total). ☛ Click the button in the lower right corner to switch between RGB and grayscale mode.
Switching between different versions enhances the illusion. The illusion does not appear to work in grayscale mode.
