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!)"_

The config file describing the glyphs is worth looking at. Also all the variable settings with comments. Pretty awesome work:

Thank you! A lot of what's possible via the configs is really tricky to specify via a URL, sadly, so I'm thinking of making a GUI to expose the rest of the knobs and switches. That's a ways down the road, though.

I'm glad the URL variable idea paid off, it makes it very easy to bookmark and share custom versions with other people ^_^

This really deserves the "made with love" attribute. That guy is insane!!!

Everyone needs a hobby! :D

A year ago, when the fourth movie's trailers premiered, I wrote a script to slice the glyphs out of the video, and then identified the new ones and redrew them as best as I could.

I missed a couple "punctuation marks" but the Resurrections version of the effect was live _ten days before_ the fourth film came out!

Lately some behind-the-scenes footage hit the web, and I was able to improve those glyphs them substantially, release a font, etc.

One could use stable diffusion or another AI to generate new characters.

Not sure why you're downvoted, the Matrix is canonically AI-generated. Any personal objection I'd have to this just cements the idea further to the fiction, you know?

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>

Shameless plug

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

https://www.dwitter.net/d/25497

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).

For those interested, the beta version of dwitter.net has an option to show the uncompressed copy of the code

The ingenuity of code golfers and other constrained coding varieties stymies me.

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.

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.

Thanks for this, it looks absolutely brilliant.

To the author - this is beautiful. If I could, it would be awesome to have a version that simulates the title of the film: the code forms up a name or a simple sentence.

Sure thing - it's amazing isn't it?

I'm considering writing a version for Windows myself if noone one points me at an existing one.. I think it could be quite fun - especially as there are quite a few neat WebL/WebGPU pages out there that would make a good screen saver.

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!

I like how marquee is long deprecated yet the MDN compatibility guide[1] shows that no one has dared drop it. Unlike its friend blink who got dropped the moment everyone hated it[2].

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.

pluc

Yeah seriously it looks so much better than GLMatrix.

rezmason
2 days

I'm open to contributing it. It'd save me the trouble of making and maintaining screensavers myself, which is a very common request. The struggle to support a Mac screensaver for more than a few years at a time has already swallowed a great Matrix project before, mathew's RedPill ( https://github.com/lpar/RedPill ).

One important matter I haven't investigated yet is what constraints there are on GL in xscreensaver as a whole. My project is basically a shader sandwich, but there are alternative approaches a port can take if that's untenable.

I also sincerely like jwz's cheeky competitiveness with other screensaver authors— when xscreensaver 4.11 was released, he captioned it, "Watch as GLMatrix makes RedPill scream for mercy." If I port to xscreensaver I'll make sure to continue the tradition.

GLMatrix aged gracefully. It has been around for a while and I still use it.

This one looks great and it would be great to see an updated version.

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

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!

rezmason

I'm glad you like it!

The original one was made by the team who produced the fancy website in '99, using the tools for making fancy websites in '99 (Macromedia Director). A noble effort!

If it had looked any better, we might have never seen the fan-made screensavers that rushed to usurp it. :D

Nice! I have something like this on my "self-hosted" website: https://subtlefuge.com/

And a more traditional green version of it as part of my interactive 404 page: https://corbin.world/404

(you'll see it after you type 'HACK THE WORLD')

I really like the 3d version of this one though, thanks for sharing!

The author clearly likes the late antiquity esoteric literature and the scripts it used.

rezmason
2 days

I sure do! The more esoteric a script is, the fewer people are around to tell you you're using it wrong.

If you're tired of the standard fare and want fresh weird alphabet, might I recommend the scripts Johannes Trithemius pulled out of thin air in his book posthumously published Polygraphiae before he died in shame in 1516? I like this chunky one:

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.
