    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.

Better MATRIX infinity remix - #spiral #quine

Show more comments…
u/Xen

nice!
u/rodrigo.siqueira

I loved it. Really. Many subtle details. And done at the right #matrix time. It is the 16th remix of a series of spirals, rings, galaxies, double spirals, explosions, torus, antennas, boids and even mountains (just follow the "remix of..."). December 22, 2021... The Matrix Resurrections. Neo + Trinity.
u/danny@hille.dk

What an absolutely delightful remix chain, I'm glad I followed the white rabbit...
u/danny@hille.dk

also made a katakana remix more in the spirit of the MATRIX -> f=g=>i*g(i/45)*g(i/t)**.1;for(i=2e3;i--;x.font=${45/t}px +x.fillText(code[i%code.length],960+f(C),540-f(S)))x.fillStyle=R(0,m=t*i/5,m*.5)
u/danny@hille.dk

I have to know, what was the creative process that lead from mountains to tadpoles?
u/danny@hille.dk

oops... this is the katakana remix x.font=39/t+'px a';f=g=>i*g(i/35)*g(i/t)**.1;for(i=2e3;i--;x.fillText(String.fromCharCode(12449+t%1*94),960+f(C),540-f(S)))x.fillStyle=R(0,m=t*i/5,m*.5)

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!

Awesome!

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

Just some interference patterns, a first scribble :)

You've reached the end.
