_Vera Molnar, Parcours à angles droit (1997)
Vera Molnar (1924–2023), the pioneering computer artist, made a number of different versions in her 1990s Parcours print series; I quite like the 9×9 version. And thinking of the cells as accordions. The fields in these prints are always drawn with a single line. (I randomized the number of oscillations in the tile sections as she would have done herself.)

As always, I built the reconstruction/animation with Python in DrawBot.
