Edges2Cats is an interactive web tool based on the pix2pix image-to-image translation model, released in early 2017 as a demonstration of machine learning capabilities. The tool allows users to draw line-art edges that an AI attempts to fill with realistic feline textures; however, because the AI forces cat features onto any shape provided, the results are frequently grotesque, misshapen, or unsettling 'nightmare cats.' The meme went viral across social media as users shared their most horrifying artistic failures, cementing its legacy as a hallmark of 'cursed' AI imagery and a humorous commentary on the unpredictable nature of early generative art.
