A furin is a small Japanese wind chime, which is traditionally hung from the eaves of a house during the summer. It has the shape of a bell with the clapper in the center of the
chime. A strip of paper, called the tanzaku, hangs from the clapper. When the wind blows, the tanzaku causes the clapper to strike the sides of the chime, thus making the furin toll.
Japanese people enjoy that furin changes the wind into sound.
However this furin is actually not under the eaves but rather in the principal's office at one of the schools I go to. She is a bit of a Japanese style freak :).
