I went through old code and found a neat lerp algorithm. Two circles rotate and a third chases the previous angle between the two moving circles. The path of the third is drawn with very low (I believe it is 5) opacity.


let v1,v2,v3,v4;
var size=1;
var rot1=30/100;
var rot2=40/200;


function setup() {
createCanvas(windowWidth, windowHeight);
background(0);

noFill();
v1 = createVector(-20, 20);
v2 = createVector(20, 20);

r+=5;

var step=.05;   

translate(width/2,height/2);

v1.rotate(rot1);
v2.rotate(rot2);
v3 = p5.Vector.lerp(v1, v2, step);

stroke((5*second())%255,(6*second())%255,(4*second())%255,5);
ellipse(v3.x,v3.y,size,size);
size+=.1;
