    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.

Golfed this one a little bit :) #symmetry
u/pavel

i=[4 bits for start circle index][4 bits for end circle index offset from start circle][1 bit to decide start vs end]
u/pavel

That's 2**9=512 which is too small for power-of-two circle sizes but start clicle index wraps around so larger i is only redundant.
u/pavel

end-circle-offset == 0 is easy to check and means start and end are same circle, so draw that circle.
u/pavel

Otherwise draw the current circle with radius 0 which is same as lineTo.
u/pavel

T=!T&&!x.beginPath(x.stroke()) starts/strokes the path every two circles.
u/pavel

Here is a version before all the bit hacking for(c.width=640,i=16;i--;)for(j=16;j--;x.beginPath(x.stroke()))for(k=2;k--;)q=(i+j*k)%16,r=((q+2)/6|0)*64,x.arc(320+r*C(a=Math.PI/3*q+t),180+r*S(a),!j*32,0,7)
