G'MIC Challenge: Create image from photographs with a single line

[lylejk (Lyle Kroll)]

Pretty cool stull, Reptorian; didn’t know you can do TSP artwork in G’MIC… If you created the preset, hope you share it in your G’MIC plugin preset. Now if someone could do a variable density Hilbert curve render (posted request below). lol

Variable Density Hilbert Curve

Does anyone have the g’mic skills to create a preset that can do this? Looks pretty cool. Also, it’s a single line fill much like the traveling salesman curves. Anyway, if so, even better if other single line fill formulas could be chosen.
