The 'Spiral Town' or 'AI Spiral Art' meme trend emerged in late 2023, following the rise of AI image generators like Stable Diffusion using ControlNet. These images typically depict seemingly normal landscapes, such as medieval European villages or dense forests, that reveal a perfect spiral pattern when viewed from a distance or with squinted eyes. The trend became a viral sensation on platforms like X and Reddit, as users competed to create the most subtle yet recognizable hidden patterns. It represents a unique bridge between generative art and classic optical illusions, often used to showcase the uncanny capabilities of modern artificial intelligence.
