## Description

cmatrix is a C-based terminal application and command line utility designed to simulate a scrolling digital rain effect. It functions as a CLI visual animation tool that renders falling code patterns and custom text displays within a terminal emulator.

The application provides options for visual style customization, allowing users to modify color schemes, font styles, and character sets. It includes animation speed control to adjust the rate of falling characters and supports rendering specific custom messages in the center of the screen during the animation.
