Looping Lemniscate

A soothing shape of lemniscate looping in an organic manner is pure bliss to the eyes.
Now, you can just stay for a moment, calm yourself down and enjoy the beauty.

Code

    elem = document.querySelector(".example-container");
    setCanvas(elem);
    t=0;
    trail=[];

    function draw() {

        clearCanvas();
        x=200*cos(t)/(1+sin(t)**2);
        y=200*cos(t)*sin(t)/(1+sin(t)**2);   //lemniscate equations

        trail.push([WIDTH/2+x,HEIGHT/2-y]); //push the coordinates to the trail array
        if(trail.length>100){
            trail.shift();
        }
        for(let i=0;i<trail.length;i++){
            new circle(trail[i][0],trail[i][1],10,'#695fe6',mapRange(i,0,100,0,1),'#fff0',0);
        }
        
        t+=0.018;

        requestAnimationFrame(draw);

    }

    draw();
