    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.

If someone can shave 2 characters off, we can invert the colors! Like in d/7011

u/akm

here, I shaved off 10 chars: with(x)for(fillStyle="#FFF",i=0;i++<44;lineWidth=44)beginPath(arc(960+S(a=t*i/11)*(d=i*t*S(t)),540+C(a)*d,i*3,0,7),fill(stroke()))
