    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

still trying to get the black background

This is wrong but perhaps you can fix it: i=1920;j=Math.abs;for(;i--;)a=(t*600-i/9|0)%999,x.fillStyle=R(0,a,0),x.fillRect(i,a?500+100*j(T(i/599))*S(j(i/90)):0,1,a?40:999)
