Adult Diary explores how new media can shape gender and identity through nine virtual alter-egos. Starting from a diary of how a non-human becomes human, I created cinemagraphs of self-portraits and let one AI infer prompts, then passed them to another AI for expansion—like a back-and-forth game with the machine. The video, blending V8 camcorder texture and 360° language, unfolds in nine roles: a thought abortionist, a gender designer, a blockchain pet-communicator, and more. It reflects on identity, gender politics, and AI ethics beyond life and death.
