    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.

Hello u/DotsnLines & everyone; maybe someone need versions this d/26627 with 90symbol: c.width+=0;for(i=1201;i--;)j=600-i,n=t/500*i,x.fillRect(S(n)*i*.75+960,C(n)*j*.75+540,8,8) and if you want get line 123symbol: c.width+=0;x.lineWidth=9;x.beginPath();for(i=1201;i--;)j=600-i,n=t/500*i,x.lineTo(S(n)*i*.75+960,C(n)*j*.75+540);x.stroke() ~_^

You've reached the end.
