    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. ;)
u/Zolden

Thank you, good point, missed that.

change C(p) to C(i) for kicks

try this... for(x.fillRect(0,0,2e3,2e3),Z=V=W=960,j=950;--j;Z=j%98-t*6+(V=t*6|0))x.clearRect(W+S(p=t+j/4-6.03*V)/Z*W-Z*9,540+C(p)/Z*W,s=99/Z,s)

You've reached the end.
