Movies
Technical information on screens in movies often is just made up random stuff.
Here are some exaples on how to create some nice visuals with no deeper meaning:
Hex Editor
Use a hexeditor like hexyl to show random information.
Install
sudo apt install hexyl
Run this
for n in $(seq 1 1000) ; do hexyl -n 512 /dev/urandom && sleep 0.1 && clear ; done
