Mapping -diff(y) to linewidth = "light on the upstroke, heavy on the downstroke" = calligraphy

More fun with OEIS integer sequences.

Today we'll make some pseudospirals: a sequence of arcs with 90 degree turns in between, where the radii are driven off a sequence. Arcs may have a gain function applied. Negative radii flip direction.

A200437: Number of -n..n arrays x(0..9) of 10 elements with zero sum and no two or three adjacent elements summing to zero
Sequence negation (every 17th), no gain

SD 3.5 large is a bit of a hit and miss experience, but ComfyUI is a surprisingly well-made software.

I had to use a tainted Linux Kernel to generate this picture, so I really do have mixed feelings about this technology which I still see as a social dead-end in terms of business. Also, I think it takes away a part of the creative process that is crucial in interesting/long-lasting art, but it looks clean.
