    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

it's fun to adjust the c.width=X value. for low values it gets very blocky, but shape position should not be affected.
u/donbright

adjust c.width with mouse: t?w=c.width=n:n=1 onmousemove=e=>n=e.pageY for(i=6;i--;x.lineTo(w/2+(Z=1/(2+C(p=1.257*i*2+t)))*S(p)*w/2,Z*w/2-w/20),x.stroke());
