Matrix rain as page background for YouTube - NOT over video or text. Includes Matrix green themed CSS styling.
# Matrix Theme & Code Rain for YouTube
## Overview
Bring the iconic Matrix movie effect to YouTube with this userscript! *Matrix-Youtube.js* transforms the YouTube browsing experience with a vivid green Matrix rain code as the page background, alongside an immersive dark Matrix green color scheme. The Matrix rain is tastefully rendered behind all content, never obscuring videos, text, or controls.
## Features
- **Live Matrix Rain Animation**
Animated Matrix-style code (“digital rain”) cascades as a background overlay on every YouTube page.
- **Matrix Color Theme**
All of YouTube adopts a stylish black-and-green Matrix look: backgrounds, buttons, menus, player, and sidebars.
- **Non-Obtrusive Design**
The rain sits *under* all content—videos, comments, and UI remain crisp and readable.
- **Custom Code Characters**
The rain uses both Japanese katakana and Latin characters for authenticity.
- **Adaptive & Responsive**
The animation and background styling adapt to window resizing and page navigation.
- **Performance Focused**
Optimized drawing ensures smooth animation with minimal resource usage.
- **Persistent Theme**
The effect persists on all YouTube subpages and responds to YouTube’s dynamic layout changes.
