    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.

Nice! Small tweak, just swinging left and right: for(c.width|=j=0;j++<9;)for(h=5;h-->-4;)for(i=5;i-->-4;x.fillRect(958+h*m*2-j*4+m*9*S(t),538+i*m*2-j*4,m+9,m+9))m=8*j,x.fillStyle=R(m,m*2)
