    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.

Nice! There are some golfing opportunities. 124 byte version...for(c.width=g=999,i=-70;40>i++;)for(j=80;--j;l(f+=500))(l=e=>x.lineTo(500+f/h,(g+270*S(7*f))/h))(f=500*i,h=j-t%1) x.stroke()
