load a Slonk, Normie, or CryptoPunk for the shape, then pick a nERVOUs from the collection (#0–2047) to fill it with that piece's real on-chain art (forced to the nERVOUs palette). slonks fill only the pixels that have MUTATED away from their base punk; the rest stay a quiet C64 ghost. pick a background, add CRT / chroma, then download the GIF.
