Greyhat -- MINIMAL #TECHNO 128 BPM GREY CODE RHYTHMS Experiment with #generative hihat rhythms. An 8-bit binary gray code is a sequence of all 256 possible 8-bit patterns, ordered such that each subsequent pattern changes by flipping exactly 1 bit of the previous pattern.

two people of sound mind entered the nameless gallery under the brooding hot autumn city heat, up the endless stairs into the choking room, they gazed upon the painting, one whispered to the other "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn ..." #generative #genartclub

Do you like oklab, but dislike numbers? Introducing: klab -- it's shorter than oklab #generative #genartclub #codegolf #glsl

More experiments with straight lines 30x30cm black ballpoint on heavy bristol paper #generative #genartclub #plotter
it's a plot made with a ballpoint pen that uses only straight lines, but they interlock in a way that suggests curves exist

Which means it looks like this, except it's in blue ballpoint, so it actually looks quite different
the same thing, rendered, higher order, it looks like a dark blob

Piter Pasma @piterpasma.nl · 06/04/2026
It's basically doing like this, but the plane filling squiggly fractal (a.k.a. "Hilbert curve") is much finer
the same thing but rendered, and the Hilbert curve is of a lower order

I made this back in 2022 (it fit exactly into a tweet). It was a few hours of battle and chipping characters 1-3 at a time. It actually blows my mind, because even with diminishing returns, I genuinely have no idea where could be the limit :)

Thanks EVERYBODY for making such an amazing GENUARY 2026!! If you did all or most of the prompts, you should be very proud -- that is a significant achievement :) And if you did a couple of them, most importantly I hope you were inspired and had fun!! #genuary #genuary2026
