Quote from the Github repo:

_"The following criteria guided the development process:

Get the right glyphs. Like the actual ones. By now everyone's heard how the Matrix glyphs are some treatment of Katakana, but they also include a few characters from Susan Kare's Chicago typeface. The Matrix glyphs in this project come from the source: cleaned up vectors from an old SWF for an official Matrix product, archived back in 2007. That's how deep this rabbit hole goes, friends. (Please support the Internet Archive!)"_

For a very simple matrix-like effect, I use

<canvas id="matrix" style="display:block; position: fixed; top: 0; left: 0; z-index: -100;"></canvas> <!-- position: absolute --> <script type="text/javascript"> var matrix = document.getElementById("matrix"); var matrix_ctx = matrix.getContext("2d"); var mletters = "01" var font_size = 10; matrix_ctx.font = font_size + "px arial"; matrix.height = window.innerHeight; matrix.width = window.innerWidth; var columns = Math.floor(matrix.width/font_size); var lines = matrix.height/font_size; var drops_reinit_threshold = 0.975; // lower value means more frequent reinit and therefore more drops var drops_y = Array(columns).fill(1); function draw() { matrix_ctx.fillStyle = "rgba(10, 10, 10, 0.04)"; matrix_ctx.fillRect(0, 0, matrix.width, matrix.height); // fade out text from previous iterations matrix_ctx.fillStyle = "#050"; // green text for(var i = 0; i<columns; i++) // i < drops_y.length { var letter = mletters[Math.floor(Math.random()mletters.length)]; if (drops_y[i]font_size <= matrix.height) matrix_ctx.fillText(letter, ifont_size, drops_y[i]font_size); else if(Math.random() > drops_reinit_threshold) drops_y[i] = 0; drops_y[i]++; } } for(var x = 0; x < 2*lines; x++) draw(); setInterval(draw, 35); </script>

Really, really well done. 3D mode was especially cool. I remember having the official Matrix screensaver (remember www.whatisthematrix.com?) and being a little disappointed that the glyphs and animation didn't seem right. This is spot on - fantastic!

Ukraine flag colors were missing but thankfully there is a custom rgb feature:

Zooming the page changes the pixelation of the rain, which is a fun detail.

The level of detail put into this project was an unexpected surprise, I've got a new bookmark after tuning it to a nice 3d blue color gradient!

I hope someone can update the xscreensaver code with this one.

The quality of the output is great! Kudos!

My favorite so far is Morpheus mode, something about moving "into" the glyphs as they fall makes me think of digital city under the rain.

For simple matrix-like effects, I use

  <canvas id="matrix" style="display:block; position: fixed; top: 0; left: 0; z-index: -100;"></canvas>
  <script type="text/javascript">
  var matrix = document.getElementById("matrix");
  var matrix_ctx = matrix.getContext("2d");
  var mletters = "01"
  var font_size = 10;
  matrix_ctx.font = font_size + "px arial";
  matrix.height = window.innerHeight;
  matrix.width = window.innerWidth;
  var columns = Math.floor(matrix.width/font_size);
  var lines = matrix.height/font_size;
  var drops_reinit_threshold = 0.975; // lower value means more frequent reinit and therefore more drops
  var drops_y = Array(columns).fill(1);
  function draw()
  {
    matrix_ctx.fillStyle = "rgba(10, 10, 10, 0.04)"
    matrix_ctx.fillRect(0, 0, matrix.width, matrix.height);
    matrix_ctx.fillStyle = "#050"; // green text
    for(var i = 0; i<columns; i++)
    {
      var letter = mletters[Math.floor(Math.random()*mletters.length)];
      if (drops_y[i]*font_size <= matrix.height)
        matrix_ctx.fillText(letter, i*font_size, drops_y[i]*font_size);
      else if(Math.random() > drops_reinit_threshold)
        drops_y[i] = 0;
      drops_y[i]++;
    }
  }
  for(var x = 0; x < 2*lines; x++) draw();
  setInterval(draw, 35);
  </script>

When I was a teen I made a way shittier version of this using a bunch of vertical <marquee> tags and exotic looking Unicode characters. I literally just copy and pasted them since I didn't know any JS. It looked great as long as you didn't inspect the code!

Shameless plug

Matrix "Trace Program Running" scene in 194 bytes of javascript

Close to authentic but not 100% due to fonts, non-linear easing of the zoom, and of course the end transition diving into the CGI 0 which is a bit beyond this size bracket of code golfing (although you kind get a modicum of the effect via aliasing).

Am I the only one that hears "Wake Up" from RATM when opens the page even though no music is playing?

It has been asked a couple times in the comments with no response so far. Would anyone have any idea on how this could be made into a desktop/phone wallpaper or screensaver?

That would be such an awesome application. :O

I made one[0][1] that uses the GitHub API to pull snippets from recent commits to use for the code. But this is much more beautiful and comprehensive on the visual front.

I tried it with this "web page as a screensaver" app and it worked perfectly.

macOS only though - I couldn't find a Windows one.

Online demo: https://rezmason.github.io/matrix/

I realized that upon seeing the animation, my mind automatically begins playing the soundtrack.

Amazing.

I, to this day, use a Digital Rain screensaver for Mac, and live wallpaper for Android ('Source Wall' on Google Play). Very happy to see this specific fandom still alive. Even after that godawful fourth movie.
