<h6 class="center">12 JANUARY 2024</h5>

<div class="threecol justify"><p>The famous digital rain from the movie The Matrix implemented in C for
the Unix terminal without using any GUI/TUI kits:</p>
<video style="max-width:100%;" controls="" poster="thumb.png">
<source src="matrix.mp4" type="video/mp4" />
</video>
<p>Domsson’s <a href="https://github.com/domsson/fakesteak" class="external" target="_blank" rel="noopener noreferrer">Fakesteak</a> inspired
this project. I added the following features while trying to keep the original
project’s simplicity intact as much as possible:</p>
<ul>
<li>Customize the rain color to match the theme of the setup.</li>
<li>Support for UTF-32 characters.</li>
<li>The ghosting effect of old monochrome displays.</li>
<li>The rain more closely resembles the original from the first movie.</li>
</ul>
<p>To use them, you need a terminal emulator that supports 24-bit RGB colors and
Unicode characters.</p>
<p>The background, head, and tail colors of the rain can be configured via
<code class="language-plaintext highlighter-rouge">COLOR_BG_*</code>, <code class="language-plaintext highlighter-rouge">COLOR_HD_*</code>, and <code class="language-plaintext highlighter-rouge">COLOR_TL_*</code> settings. The <code class="language-plaintext highlighter-rouge">UNICODE_MIN</code> and
<code class="language-plaintext highlighter-rouge">UNICODE_MAX</code> values control the character set used for the rain. For instance,
use <code class="language-plaintext highlighter-rouge">0x30A1</code> and <code class="language-plaintext highlighter-rouge">0x30F6</code> for Katakana:</p>

<p>Happy ricing!</p>
