Full screen terminal with script as screen saver under archLinux

Bonjour, Is it possible to run a terminal at full screen running a script instead of the screen saver ? That means that after 10 minutes of inactivity the screen should go black and show the STDOUT of a script (ex cmatrix or fortune), and then go away when clicking with the mouse / with a keystroke. I'm running Antergos (ArchLinux) with the last version of Gnome. If you have any ideas on how I could do this, I would really appreciate.
