Move multi-character ascii images with bash
 

Am looking for a way to move multiple character ascii images on the screen using Bash scripting.
Not interested in software that does this but a technique to encode it.

You will need to look at curses programing which is used to move the cursor round the screen, set colours etc all controlled from simple bash echo commands, but any sort of animation of even moderate sized images is going to be slooooooow in bash.

Have look here:
