I was listening to KUSF today, when the dj started playing this weird Sea Organ music. I had to look it up...
"The musical Sea Organ (morske orgulje) is located on the shores of Zadar, Croatia, and is the world’s first musical pipe organs that is played by the sea. Simple and elegant steps, carved in white stone, were built on the quayside. Underneath, there are 35 musically tuned tubes with whistle openings on the sidewalk. The movement of the sea pushes air through, and – depending on the size and velocity of the wave – musical chords are played. The waves create random harmonic sounds."
That description is from oddmusic homepage, which has some other great instrumentation listed in the gallery section, like the gas tank orchestra and the Excedrin thumb piano.
