    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.

You can replace 'a=993;b=S(t*a)*30;m=b*b;' with 'a=1920;m=S(t*a)*30;m*=m;'. This way your effect can cover the entire canvas width. ;)

Thank you, good point, missed that.
