The Rae NFT that wraps the chromie squiggle is a GIF, which is low res and not interactive (mouse/keyboard inputs). Instead the Rae could be coded in Javascript and embed the actual squiggle p5.js code. This would perfectly reproduce the art in a high quality + interactive way. The code could also be on-chain. I coded a proof of concept: https://octal.art/tessera-chromie-squiggle
Same idea for SVG art (e.g. cryptopunks). The Rae wrapper can be on-chain SVG.
