    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.

Cool! Here's the same with 120bytes if your or someone wants to add color...for(c.width|=y=38;y--;)for(d=2;--d;x.fill(new Path2D(V)))for(V='M',w=33;w--;)V+=[60*w,S(t+(y+d)/5+w/2)*50+30*y+30*d]+'L'

Thanks for the golf, I'm afraid Path2D strings are a bit over my head at the moment, but I did manage to golf it to 108 chars without using them. :)
