looking through these I realize that I like the one's made in p5js less.
While generally using the same techniques, just JavaScript + canvas worked a lot better. With it I made different decisions about resolution, line width and background color, while p5js' canvas scaling just kind of makes it look ugly zoomed in :p (and discourages higher resolutions maybe?)
All of the high res thin lines stuff is made using just vanilla js canvas functions, the kind of thicker lines, lower resolution is mostly p5js. And in one example I even kept the ugly gray default background color D:
