How do I configure zone-mode to run only one (or a selection of) programs?

Hi all, I've setup zone-mode to trigger after some minutes adding (require 'zone) (zone-when-idle 120) to the init file, and it works sweetly to obscure the text and prevent casual snooping... most of the time. Some of the zone modes are quite readable, or very slow to become obfuscated. Is there a way I can setup zone so that it'll always run the same program (for instance, zone-pgm-jitter) or, even betterm, a list of programs I choose? I've googled around but I didn't find any pointers to that.

C-h v zone-programs RET

Thanks!

Note that `zone-programs` is a [vector](https://www.gnu.org/software/emacs/manual/html_node/elisp/Sequences-Arrays-Vectors.html)

What implications does that have?

You cannot call the often-used list-supporting functions such as `car`, `nth`, `concat`, etc... on it. You must use functions that support vectors (sequences) which can be found [here](https://www.gnu.org/software/emacs/manual/html_node/elisp/Sequences-Arrays-Vectors.html).
