You can make a moss "milkshake" or "slurry" out of moss and beer, and then "paint" moss on whatever you would like to be delightfully green and fuzzy.
I mean who wouldn’t want a moss milkshake
I'm pretty sure moss is revered in European cultures. Like, ahh, a nice carpet-like thing to sit on in the lovely forest, instead of just a cold, hard rock.
The rolling stone rolls echoing from rock to rock; but the rolling stone is dead. The moss is silent because the moss is alive. -GKChesterton
I think it's just an agreed fact that moss is cool. What's not cool about a plant carpet.
