The fine people at Sindanorie have used Tolkien's languages to write original poetry, translate lines given in English by Tolkien into Sindarin, and create things like Elvish haiku. Go! Refresh yourself in the emo-heaven that is Elvish poetry! And remember:
Minniel arthon ere, gwannathon os-san ereb.
Having entered the world in loneliness, lonely I shall depart from it.
