Peter, this link (here) (another one from Sorcha's posting of links above) has some really gorgeous, close-up pictures, and a sound bite too.

Several years ago, a guy who lived on one of the islands in the Puget Sound built a 6-7 foot Aeolian harp and set it out on a rock spit at the edge of the water. (CRS, can't remember his name...John P, do you know?) The harps do indeed make beautiful music.
