I was wondering if there was a way to do 2d animation like a paper flipbook in real life, only in the console. I can do some programming, but what I wondered about was scroll rate?

Yes, it's possible.

GNU coreutils includes a sleep command that accepts decimal seconds, and so does Python.

So what have you tried and where are you stuck?

There are also libraries that will transform a video into something that plays in a terminal. Or video drivers for terminal.
Have a look at libcaca, or try this:

Thank you all for the feedback and new input...
1. Found python software such as clippy: https://pythonawesome.com/create-ani...-command-line/

2. found a Turn any image into ASCII art! (Easy Python PIL Tutorial)


misc..
and found out where the source code to an animated ascii project is... am not stuck so far, am curious to see how the files, and how the ascii art is written to the screen (libcaca looks helpful, thanks)... will have to try to dig through the code and libraries...

So far a basic algorithm from clippy seems to be:
Step a: write the first text file to the screen.
Step b: compare 2 text files and
step c.if the 1st file is different write the changes to the screen.
in the correct columns and rows,
also control timing and error trapping

Notes: hopefully a file cache is available for RAM and screen memory because writing to disk input-output would be slow and lessen the life of the disk
Thanks

As far as a terminal screensaver is concerned, have a look at this repository (screencast).
