    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.

Reminds me of an old-school demo effect - for(c.width|=d='DWITTER',i=d.length;i--;)x.font=${499-i*40}px arial, x.fillText(d[i],500+i*100+S(t*3+i)*300,500+C(t*5+i)*100);
