While this may not be as snazzy as many of the technical gizmos to be
found on the web, this hydraulophone is a fun work.  The co-creator,
Steve Mann, already has an extensive body of work in human-computer
interfaces, but this musical instrument seems to be something just playful.
To create a piece that directly involves individuals only at their
whim, is simple and elegant and also serves as art is something I
admire.
