    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.

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/leafyvez

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

u/lewdev

How? This is really cool.
u/joeytwiddle

I remember on some devices, fonts over a certain size just don't show. A workaround is to use a scale transform, or reduce the canvas size.

u/ivylab

I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.
u/KilledByAPixel

👍

#default on a sphere

u/f8f82804

#d3 #sphere #perspective
u/katkip

how lol
u/pavel

I draw #default one pixel at a time and treat (x,y) of the pixels as angles (a,b) in spherical coordinates. Spherical to 3d cartesian is x=r*sin(a)*sin(b), y=r*cos(a)*sin(b), z=r*cos(b). Projecting 3d to 2d cartesian is x'=x/(2+y/r), y'=z/(2+y/r), and scaling pixel size by 1/(2+y/r)**2 so stuff in the back is smaller.
