    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.

d/5673 is really cool to edit. most notably with how t is used in the trig functions; which functions are being used, and where they're used)

Got this while trying to shorten this one: c.width=1920;p=Math.PI*2;x.beginPath();t/=4;a=540;for(i=0;i<250;i++){b=p*(i/270)*T(t);x.lineTo(i*8,a+a*S(b));x.lineTo(i*8,a+a*-S(b))}x.stroke()
