Illusion Diffusion HQ 🌀

Generate stunning high quality illusion artwork with Stable Diffusion
A space by AP [Follow me on Twitter](https://twitter.com/angrypenguinPNG) This project works by using [Monster Labs QR Control Net](https://huggingface.co/monster-labs/control_v1p_sd15_qrcode_monster). Given a prompt and your pattern, we use a QR code conditioned controlnet to create a stunning illusion!
