I would suggest to code this as separately as possible, maybe even as a separate plugin. I do not think that zsh is the right language to implement Turing’s morphogenesis, but I think that you are not the only one wanting a screensaver in a terminal. So the idea is that code which deduces when to run the screensaver, switches to alternate screen, renders the screensaver and disables it should know a single thing about Turing’s morphogenesis: that it needs to run `$SCREENSAVER_COMMAND $LINES $COLUMNS` to get the screensaver rendered.

I am not the one wanting screensaver in the terminal though, so I will not participate. I am sometimes answering questions on this ML though.
