Lately I've been experimenting with generating pseudo random text. Using two inputs via scripts which use dadadodo https://www.jwz.org/dadadodo/. Interestingly dadadodo is installable on Debian/ubuntu based systems by just doing 'sudo apt install dadadodo' , which makes life a lot easier. The script runs from a terminal and uses a randomiser which chooses between 1 to 3 lines from the top of the file writes those to a holding file then deletes those 3 lines from the top of the source files then adds them back at the bottom ( the script loops until you stop it). Dadadodo randomizes the intermediate file and saves that to a temporary file then we use xdotool to write that to a vim window . Two scripts fight against each other to generate pseudo random Asemic text like this below :

Source texts
The two source texts used were Lewis Carrols 'Alice in wonderland' and William Hope Hodgsons 'The house on the borderland' sourced from Project Gutenburg project.
The scripts
There are 3 scripts to run this, I've renamed the source texts as source.txt and contra.txt . The first script is started from the command line and calls the other two scripts in a specific way. They run on an infinite loop until stopped.
starter.sh
lxterminal -e ./test.sh & xterm -e vim & lxterminal -e ./contra.sh
test.sh
#!/bin/bash
#./contra.sh
for (( ; ; ))
do
#rm new.txt
#rm inter.txt
n=$(( $RANDOM % 2 + 1 ))
f=$(( $RANDOM % 2 + 1 ))
#read first n lines of source file
find . -type f -name 'source.txt' | while read filename; do sed -n '1,'$n'p' ${filename} > inter.txt;
#shuffle n lines to end of file and delete those lines from top of file
sed -n '1,'$n'p' ${filename} >> source.txt
#strip $n lines from top starting at line 1 ( to avoid using the same lines over and again)
sed '1,'$n'd' ${filename} > swap.txt
# replace original source with swap
mv swap.txt source.txt
# Do the magic mangling
dadadodo -c $f -p 3 -w 50 inter.txt > new.txt
# type it into a vim window !!
WINDOW_ID=$(xdotool search --name vim)
xdotool windowfocus --sync $WINDOW_ID
xdotool type --file /home/crash-stop/repeater/new.txt
sleep 10
done

contra.sh
#!/bin/bash

#shuffle n lines to end of file and delete those lines from top of file

#strip $n lines from top starting at line 1 ( to avoid using the same lines over and again)
