Motivation

While working on a completely unrelated task, I wanted to share a screenshot of my current Emacs frame, but not of the actual text contents. And while GIMP’s pixelate filter did the job, I didn’t want to fire up my image manipulation program just to share a picture of a custom theme or some functionality.

I thought that Emacs must have some functionality to hide certain information on the displayed text. I remembered toggle-rot13-mode, but anyone interested in the text could decrypt it rather quickly. So instead, I had a look into its implementation and put my Emacs Lisp hat on to find my own solution.
