I think it’s the mobile-phone camera version of a double exposure. AI in the sense that it’s the camera software that automatically tries to stitch together a single image from a long exposure of something in motion, probably in low light conditions. Someone who knows more about it correct me if I’m wrong, of course. But I have some images of my (one) cat with two heads like this just from taking a pic of him at dusk with my phone using default camera settings. They weren’t so perfectly and humorously aligned as this one though!
