Matrix Digital Rain

Do not try and bend the spoon, that's impossble. Instead, only try to realize the truth. There is no spoon.

-- Spoon Boy

Overview

Pure C implementation of the famous digital rain effect from The Matrix series for Linux inspired by fakesteak. While trying to keep the simplicity and lightweightness of fakesteak as much as possible, I have added the following characteristics.

• Simulation pattern is closer to the one seen in the background while Neo and Cypher were talking in the first Matrix movie.
• Ghosting effect of monochrome displays.
• Truecolor support and simple colour customisation options to match the theme of the setup for ricing.
• Unicode support.

Requirements and Dependencies

• Terminal emulator with support for 24-bit RGB colours and unicode characters.

Customisation

• Character set: set UNICODE_MIN and UNICODE_MAX for the unicode block you like to use (e.g. 0x30A1 and 0x30F6 for Katakana):

• Colours: set the RGB values of COLOR_BG_*, COLOR_HD_* and COLOR_TL_* for background, head and the tail characters respectively.
• Rain attributes: set RAIN_RATE and RAIN_DENSITY to change the speed and the density of the rain.

Building and Running

All the code is in a single file (src/main.c) and has no external dependencies. You can compile it any way you like. If you have autotools installed you can build and run using the following commands.

autoreconf -i
cd build/
../configure
make
./amx
