-          <h6 class="center">22 AUGUST 2022</h5>
+          <h6 class="center">21 DECEMBER 2025</h5>
           <br>
-          <div class="twocol justify"><p>Over the weekend, I came across Domsson’s <a href="https://github.com/domsson/fakesteak" class="external" target="_blank" rel="noopener noreferrer">Fakesteak</a>: a beautifully lean rendition of the
-Matrix rain in raw C using ANSI escape sequences—zero dependencies, not even
-ncurses.</p>
-
-<p>To keep things simple, Fakesteak didn’t support Japanese characters and that it
-used 8-bit color mode. The latter meant that the ghosting effect has to rely on
-different foreground colors rather than shades of the same color. As a tip of
-the hat to Domsson’s impressive work, I decided to add Unicode and 24-bit
-truecolor support to it, aiming to faithfully recreate the original Matrix from
-the first movie during Neo and Cypher’s conversation:</p>
+          <div class="twocol justify"><p>The Matrix digital rain implemented in raw C using ANSI escape sequences with
+zero dependencies—not even ncurses.</p>
 
 <video style="max-width:100%;" controls="" poster="poster.png">
   <source src="matrix.mp4" type="video/mp4" />
 </video>
 
-<p>Adding Unicode support via <code class="language-plaintext highlighter-rouge">wchar_t</code> and <code class="language-plaintext highlighter-rouge">wprintf()</code> was easy enough.
-Implementing the ghosting effect with truecolor support, however, turned out
-harder than expected. To achieve the ghosting effect, I treated phosphor decay
-as a multiplier, which allowed me to emulate the dim afterglow by gradually
-transitioning each raindrop’s color towards the background color:</p>
+<p>This is a fork of Domsson’s unique rendition of the Matrix rain: <a href="https://github.com/domsson/fakesteak" class="external" target="_blank" rel="noopener noreferrer">Fakesteak</a>. Three years ago, I forked his project
+and added truecolor and Unicode support. I also drastically modified the
+algorithm to produce a rain that resembled the original aesthetic with high
+visual fidelity.</p>
+
+<h2 id="unicode-support">Unicode support</h2>
+
+<p>Unicode support in the 2022 version lacked flexibility. The charset used in the
+rain had to be a single contiguous block defined by <code class="language-plaintext highlighter-rouge">UNICODE_MIN</code> and
+<code class="language-plaintext highlighter-rouge">UNICODE_MAX</code> settings:</p>
+
+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#define UNICODE_MIN 0x0021
+#define UNICODE_MAX 0x007E
+
+static inline void insert_code(matrix *mat,
+    size_t row, size_t col) 
+{
+    mat-&gt;code[index(mat, row, col)] = rand()
+        % (UNICODE_MAX - UNICODE_MIN)
+        + UNICODE_MIN;
+}
+</code></pre></div></div>
+
+<p>There was no way, for instance, to use both ASCII and Katakana at the same
+time. The user had to pick one. In the new version, the user can use any number
+of Unicode blocks using <code class="language-plaintext highlighter-rouge">glyphs</code> array. In fact, the default rain now includes
+both ASCII and half-width Katakana characters:</p>
+
+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#define UNICODE(min, max)  (((uint64_t)max &lt;&lt; 32) | min)
+
+static uint64_t glyphs[] = {
+    UNICODE(0x0021, 0x007E), /* ASCII */
+    UNICODE(0xFF65, 0xFF9F), /* Half-width Katakana */
+};
+
+static uint8_t glyphlen = (sizeof glyphs) / (sizeof glyphs[0]);
 
-<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>static void mat_shade(matrix *mat, size_t row, size_t col) 
+static inline void insert_code(matrix *mat,
+    size_t row, size_t col) 
+{
+    uint64_t block;
+    uint32_t unicode_min, unicode_max;
+
+    block = glyphs[(rand() % glyphlen)];
+    unicode_min = (uint32_t)block;
+    unicode_max = (uint32_t)(block &gt;&gt; 32);
+
+    mat-&gt;code[index(mat, row, col)] = rand()
+        % (unicode_max - unicode_min)
+        + unicode_min;
+}
+</code></pre></div></div>
+
+<p>Entries in the <code class="language-plaintext highlighter-rouge">glyphs</code> array are Unicode blocks bit-packed in an 8-byte
+container: the four low bytes forms the first codepoint and the four high bytes
+the last.</p>
+
+<h2 id="phosphor-decay">Phosphor decay</h2>
+
+<p>The dim afterglow of monochrome CRT displays is achieved by carefully scaling
+the RGB channels individually and mixing them:</p>
+
+<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>#define DECAY_MPLIER  2

-<p>Looking back at the implementation, there are still a few improvements to be
-made. Instead of using a dedicated buffer, I should have bit-packed the
-phosphor decay into the RGB data buffer to save memory. I’m not entirely
-satisfied with the Unicode support as it’s restricted to contiguous code
-points. The glitch effect, which I implemented with characters unexpectedly
-changing, would have been closer to the original if flashed white as well.</p>
+<p>The blending function emulates the phosphor decay by gradually transitioning
+each raindrop’s color towards the background color. The multiplier is the
+number of passes over the rain track needed before the afterglow disappears.</p>

 <p>Nonetheless, the rain resembles the original with high visual fidelity. It’s
 highly customizable and gentle on the CPU. On my 14” ThinkPad T490, which has a
