Hi All,  For months I have been toying with the idea of making a
machine that plays strings with air jets instead of hammers.  I was
looking for some way of making sounds without using organ pipes or
reeds.  Well, today I found it has been done already to some degree.

The unit is called a Aeolian Harp.  The unit is placed in a window or
somewhere air flows.  The air flowing through the unit vibrates strings
which cause sound.  This seems to be a really old idea!  For more info
and some other fun, check out the following links.
