I played around with ASCII art packages that can be created from the command line.
- ASCII art packages
apt-get install cowsay
apt-get install figlet
apt-get install toilet
apt-get install jp2a

Figlet x Toilet
Figlet x Toilet can do some interesting things.
watch -n1 "date '+%D%n%T'|figlet -k" while true; do echo "$(date '+%D %T' | toilet -f term -F border --gay)"; sleep 1; done
Every 1.0s: date '+%D%n%T'|figlet -k Fri Jul 21 18:28:15 2017

jp2a
jp2a can convert images โ ASCII art.
The precision is quite good, I was impressed.
NAME="image.jpg"
jp2a --width=200 -f -i $NAME | tee AA_$NAME.txt
โOpening the text file in an editor looks like this.
