A minimalist token I coded as a form of break from the complexity of my next project. Below you can find the 33 lines of p5.js that generate all the variations of this piece: they may seem more than 33 due to some of them exceeding the page width; zoom out and you'll see that they're really 33 ;)

let h,a; function setup() { colorMode(HSB); randomSeed(fxrand()9999999999999); createCanvas(min(windowWidth, windowHeight), min(windowWidth, windowHeight)); h = random(0,360); a = fxrand()<0.5 ? random(0.01,1) : 1; let mono = fxrand()<0.5 ? false : stro(); let d = random(1,50); let s = fxrand()<0.5 ? random(15,300) : random(300,1000); let n = random(0.01,1); let focus = random(0,width); for (let y=0; y<height; y+=height/(random(30,s))) { let sat = random(30,100); if (!mono) {stro()} for (let x=0; x< width; x+=width/(random(1,s))) { let d = dist(x,y,focus,y); fill(color(h,sat,map(d,0,width/2,0,100),a)); rect(x,y,width,height); sat = adj(sat,0,5,30,100,false); } h = fxrand()<n ? adj(h,-d,d,0,360,false) : h; focus = adj(focus,-width/(d0.5),width/(d0.5),width0.1,width*0.9,true); } fxpreview(); } adj = (c,d1,d2,start,end,rebound) => { let ac = c+random(d1,d2); ac = ac<start ?
