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)

This is what we see when we fly on the Neverending story's dragon (Falkor flight). Watch while you listen to Neverending Story or Bastian's Happy Flight. See remix link for the night version.
