Text crawl and other effects GLSL shader

For my project, I've been working on a kind of 80s style sci-fi monitor display.In game, this is going to be handled by a single texture effect with a GLSL shader. Different sections of the texture will be cut down and used on different view screens. Here's a preview of how it looks in action: Screen capture in Linux Mint is always a bit buggy. :( Or maybe it's because my computer is over ten years old... Here's another set of screens with different colors and contents, for the planet that the player gets to visit in the first episode (you can see in this preview how the "alert effect" is activated to change colors of the scan): You can see the original effect I'm trying to duplicate in the Star Trek movies: Anyway, it's a nice set of old school effects, and I'm going to explain how they are achieved in a game engine with a GLSL shader (In this case, GODOT, and awesome free game engine). First you need to set up the different layers of your image.
