    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.

does this diagram have a name? #waitforit

u/farter

finally with compressor from d/17775 , now draws incrementally non-repeating, just nicer! go fullscreen for more details.

don't stare at it for too long cuz the amount of drawing grows quadratically.
u/farter

adjust viewport to get more complete view of its beauty~
u/farter

better performance & smoother graphic but can't golf.... t?n=t+2|0:l=0;if(l<n){l=n;for(i=l;--i;)for(j=l;--j;)u=Math.PI/l,k=n-i-j,k>0&&(z=960/(1/T(u*i)+1/T(u*j)),r=48/l,x.fillRect(z-r,60+z/T(u*i)-r,r+r,r+r))}
u/farter

this needs 3 secs wait. updated version at d/24464
u/farter

for really nonrepeating drawing, only draw when i,j,k are coprime.
u/joeytwiddle

l=60*t|0 can speed it up (but don't leave it running too long)
