You don't need to spend a fortune, let's say ~230€, to have a pen plotter. Get a vinyl cutter, a cheap machine will be fine, it's a lot of fun in a small space. Get one with a pen USB port. https://blog.nexp.pt/penplotteronthecheap.html

Eheh the filter algorithm just misbehaves sometimes :) I do like it!

algorithmic generated physical drawings ・continuous series of pen plotter drawings ・ generated with an original line drawing algorithm seeded from photographs, txt2img images or 3D rendering models・ these NFTs come with the original pen plotter drawing to be claimed by the token holder via Arfora. https://objkt.com/collections/KT1CUAZALU4hVSFuxh5U1cdMvLYtaHBMAUU9

'Often I am asked "Who are the algorists?" Simply put an algorist is anyone who works with algorithms. Historically we have viewed algorists as mathematicians. But it also applies to artists who create art using algorithmic procedures that include their own algorithms.' RV http://algorists.org/

Completeness and determinism in algorithms are aesthetically categories that push into the limit of what can be described, fragile pedestals for our random existence. https://www.fxhash.xyz/generative/31146

Also implemented is a coarse grain operator (CGO) that permits to morphologically zoom in and out of the pattern. The coarse grain operator has two parameters: a scale, parameter 'CGO scale' and an exponent, 'CGO exponent', that roughly specifies the magnitude of the coarse grain operator. 'CGO scale' equal to 1 (one) disables the coarse operator.

One of the visual appealing parameters of the algorithm is the roughness exponent which is closely related to the fractal nature of the patterns produced. This roughness exponent shapes the resulting spatial pattern morphology, larger values of the exponent leads to coarser patterns, the inverse also happens, lower values of the roughness exponent leads to finer detail. These mathematically structures, patchwork quilts, are fractals with self-affine properties arising by simple bitwise operations between numbers.
