Varúð = Caution.
Morse code in video is apparently:
“It doesn’t matter what I say”
“The only thing that matters is how you feel”
“Understanding that the words are irrelevant is of great importance”
“What feelings do you have”
Why Caution? What danger are they trying to protect us from? The fact that morse code is used just emulates a more mysterious and foreboding atmosphere. Words fall away and there is nothing left that can help us communicate but this desperate - almost agonizing - substitute for the spoken voice. What if i wanted to cry? What flickering light can communicate to you my despair? Faces fall away. We’re just another black silhouette slumping up into view, overwhelmed by the coarse, dark features of the landscape where rocks and cliffs hold nothing but danger. When all of this fails, we surrender the light, and retreat, slouching back into the dark where at last we surrender to silence.
