    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.

a bit golfed: c.width=800;for(i=0;i<50;)x.lineTo(a=S(i+t)*100+400,b=C(t+i)*C(i++)*100+300),x.fillRect(a,b,1,1),x.stroke()

You've reached the end.
