+My version of the matrix has the following features:
+
+ - Unicode characters.
+ - Fully customizable 24-bit RGB (truecolor) colors.
+ - Glitches in the matrix.
+ - Ghosting effect of old monochrome displays.
+ - Closely resembles the one seen in the background while Neo and Cypher were

+As there are no dependencies, you can compile and run it however you want:
 
 ```
 $ cc -O3 main.c -o matrix
 $ ./matrix
 ```
 
-While I loved Domsson's take on the
-digital rain, what blew my mind was the minimalistic elegance of his code. As I
-carefully examined it, I thought about what it might take to recreate the
-original digital rain from the first Matrix movie with it. The challenge is
-adding these features without destroying fakesteak's elegance.

 ## How does it work?
 
-The `matrix` struct makes use of three 2D arrays to encode the Matrix: the
-`code` array for 32-bit Unicode characters, the `rgb` array for 24-bit RGB
-values of the character (foreground color), and the `shade` array for the
-degree of transparency of the character to simulate the ghosting effect of old
-monochrome displays. The dimensions of these arrays depend on the size of the
-terminal screen. Each slot in the array corresponds to a cursor position on the
-screen.

 The ghosting effect, which is arguably the crowning feature of my version, is
 implemented by carefully scaling and mixing the RGB channels:
