A Raycaster in Bash

Imagine a TUI where you need to navigate a literal maze of options

Many CLI programs which take option have already managed to do this (in the text-based adventure game style).

That's the kind of "futuristic interface" you'd see in a cyberpunk movie, and it would be incredibly annoying in real life.

Like this one in Jurassic Park? https://youtu.be/URVS4H7vrdU Funnily enough, the slow rendering is kind of a plot device here.

The program from that scene was not some crazy invention for the purpose of having an interesting computer scene. It is a real piece of software for silicon graphics workstations called fsn (File System Navigator).

There's a x windows remake of it called fsv: https://fsv.sourceforge.net/

And then there's this even cooler UI which takes this whole idea much further called eagle mode: https://eaglemode.sourceforge.net/
