    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.

x.rotate is shorter, as usual for(t*=7200,i=420;i--;x.fillText(j=i/12|0,j,15*S(j*j*t),4))x.setTransform(1,0,0,i%12<6?-1:1,t%1980,t/24),x.rotate(i%12/.954)

Thanks! I will use that method for the next iteration
