Did you see the library of viz? https://github.com/attogram/bash-screensavers/blob/main/libr...

My favourite API: lov_die_with_honor()

(thought I'd share that since its raison d'être was to put Asciiquarium there :))

Screensavers are a lost art. I still enjoy them, but at some point we just gave up on them. In the era of CRTs they had a practical purpose (they're screen savers, after all), but modern OLED displays also suffer from burn-in for which screensavers would be useful. My enjoyment is purely aesthetic, though. Sometimes I just want to have something pleasing to glance at in the background, instead of a black screen.

Nowadays most operating systems and desktop environments don't even support them. The state of the art on Linux still seems to be `xscreensaver`, which does have many great ones, but the collection is static, and most of it is visually stuck in the 90s. I wouldn't even try getting it to run on Wayland, and when I last looked into it, it required some hacks and 3rd-party tools.

Also, I've always found the feature of screen locking and screen saving to be orthogonal. Often I want to see pretty graphics without locking my screen, and viceversa.

Also, found one of the easter eggs!

    > /home/keeb/code/projects/login/motd.sh

    #!/usr/bin/env zsh

    values=("bubbles" "slide" "beams" "rain" "pour" "synthgrid" "unstable" "poop")
    len=${#values[@]}
    index=$(( (RANDOM % (len - 1)) + 1 ))
    selected=${values[$index]}

    cat /home/keeb/code/projects/login/motd | tte $selected

First feature request: allow disabling all the `tput setab 0` calls throughout the codebase. This may make screensavers look weird on white terminals but should improve them for anyone using non-black-but-dark terminal themes.

    #!/usr/bin/env bash

    _cleanup_and_exit() {
      tput cnorm
      tput sgr0
      clear
      exit 0
    }

    trap _cleanup_and_exit SIGINT

    while true; do
      width=$(tput cols)
      height=$(tput lines)

      tput setab 0
      clear
      tput civis

      x=$((RANDOM % width + 1))
      y=$((RANDOM % height + 1))
      color_code=$((RANDOM % 256))

      printf "\e[${y};${x}H\e[38;5;${color_code}m"

      sleep 1
    done

A lot of screensavers, even historically, forget the original purpose of what "saving" your screen means.

What are those commit messages?

(at least when running in docker, maybe that's the bottleneck, but I hesitated to run this on my machine directly)

I get "mapfile: command not found"
