    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.

Improved version with less bright problem around the black lines: c.style='filter:sepia()invert()';for(A=X=Y=t,i=7e4;i--;x.fillRect(1680-X*15,Y*15+540,.1,t<1))Y=(i/Y&8)*6+(Y-X)/2+.8/Y*S(Y*i),X+=Y
