    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.

Mandelbrot Tracer ASCII Art #ascii #mandelbrot using p01 and xen ideas

Code from "Mandelbrot Tracer - Possibly the smallest Mandelbrot tracer ever in JavaScript": http://www.p01.org/128b_mandelbrot/ (Mathieu 'p01' Henri page), u/p01 citing u/xen

😍 My very first golf

Cool. I love text rendering... I actually tried something like that... but less golfed and more primitive... if you'd like to comment on it: http://andval.net/julia_v2_4.html
u/rodrigo.siqueira

I like your page and code u/andrea270872, it's nice to see the parameter changes and ASCII ART rendering. Please see mine ASCII ART Mandelbrot and Julia Sets, color, including "POETRY" option, clickable, zoom, and other control options: http://www.fractarte.com.br/cgi-bin/ascii-fr… (it was made 19 years ago, I only updated the link to my Dwitter profile!) It's made in PERL, if you want I can send the source code if you want to convert it to JavaScript.
u/andrea270872

Wow. I have to play with it! Terrific use of text and colors. The dithering with the Xs looks like stitching... very nice.
u/rodrigo.siqueira

I updated the code to remove the "stitching" effect. It's here (color ascii art mandelbrot and Julia Set): https://bit.do/ascii-fractal
