ASCII screensaver for the command-line or a TUI?

This question was closed due to being too broad, so I'll be more specific with regard to ASCII animations here =)

Are there any ASCII animations that can be used as screensavers - either in the TUI or in the command-line?

Note: Although I do not show it in the images here, it is animated.

And if you want it to work like a proper screensaver (though the -l option won't work) then check out this answer.
