Next is @baabbaash speaking about "Zigzag Mosaics and Single-Line Drawings." He shows us how to create #MathArt from single-line drawings (paper here: https://archive.bridgesmathart.org/2024/bridges2024-335.html#gsc.tab=0). The trick is to modulate the zig-zag of the line to make it lighter/darker at a pixel.
