Idea: shh

It's ssh but nothing displays on the screen.

@Haxk20 the rabbit hole goes even deeper.

Hit a wired quartz crystal so hard that it generates enough power to send electrical signal to an Arduino.

The arduino has a "Morse code to ASCII converter" program.

You hit the quartz crystal in the way you would use Morse code and install arch linux that way with shh.

No keyboard. No displayed stuff. Just you, your hand, the crystal, the converter and shh.
