Could it be an Emacs screensaver?

Maybe it would do a good zone screensaver too

I had a prototype zone-pgm-secret-mode, but unfortunately it didn't work as intended. Maybe version 0.3 or so can provide a new zone method :)

Hey @Ypot, just making sure: the zone screensaver should remap all characters at once (see #7) or replace the characters one after another?

Hey!
I think it would add real privacy if all characters would be replaced at once.

Edit: Or at least in few seconds (customizable?), that could be quite attractive, like when a virus "eats" bits of information.
