    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.

Minor tweak idea ->x[s='fillStyle']=R(z=c.width=300);x.fill(x.arc(p=150,S(t/9)*20+30,13,0,7));for(i=z;i--;x.fillRect((i+t*66/i)%20*20-z/i,160,z/i|8,-i%S(i)*p))x[s]='#fff1',x.fillRect(0,S(-t/4)*30+i^4,z,i),x[s]=R()

1282675 encodes the 'turn right' or 'straight' orders in binary, >>f&!(f%1) checks them on frames when f is an integer.

Satisfying, looks like a recursive "Bowen Knot"

Oops, you have to flip X and shift it a bit, then it's -1
u/pavel

If you start with 0 and simultaneously replace 0 with 1 and 1 with 001 you will generate this sequence and bigger ones.
u/pavel

Similarly, if you start with 1s and replace s with s1s00s1s and ignore s when drawing.

I invented the second method. The first one I found by putting my hand-made small sequence into https://oeis.org .

Some nice math for the 270 initial radius: The half-height is 540, this must equal r+r/2+r/4+r/8+...=r(1+1/2+1/4+1/8+...). Think about the bit in the brackets in terms of pizzas. You have a whole pizza, plus half a pizza, plus a quarter (half the remaining half), plus an eighth (half the remaining), etc. You have two pizzas! So 540=r*2.
