    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.

first time, ever, i've seen an improvement on any of pavel's designs :)
u/tomxor

True, Pavel's dweets are pretty tight. Usually the most I can hope for is -1 char :P
u/tomxor

d/24387 restored the slow draw, and removed the for loop for only +1 char

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

Satisfying, looks like a recursive "Bowen Knot"
u/leafyvez

so beautiful
u/rep_movsd

This looks like the traditional "kolam" that Indians traditionally draw in front of the house
u/rep_movsd

Changing that 1282675 makes different patterns

u/rep_movsd exactly my thoughts!

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.
u/pavel

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

It's the command key but more complex
