I would probably have to recreate that effect. The last time I found something like that for G’MIC. I noticed it only has one pixel strokes. I create filters by theorizing and then applying it unless I don’t have anything to go off by. For me, comparison is necessary to validate that there is improvement. Sometimes, I go too far by going into 30+ controls like for the Vibrato and the OOBS filter (I doubt most people bother with those, but they’re there for any one who likes flexibility and need those).
EDIT: On second thought, I think I might to recreate a shape based effect where tiles contains shapes into them and each tiles has two colors.
