It had to go through around 45+ iterations, over various cups of tea, with small tweaks before I was satisfied. It's in the G'mic github repo, and also available with some instructions for newbies who are exploring this filter on my github.

You can find it in the Artistic menu. Happy Dreaming!

I do not have a bone of coding in me. So needed to get some help. Coded entirely with Claude Sonnet 4 & 4.5. Took me around 3 weeks of research on Claude, Mistral, Qwen & Gemini.

Thanks.
