A friend of mine put tissue paper in the path of the air above the
windway on each pipe on his small monkey organ.  They fluttered each
time the pipe sounded.  I thought this was a great idea so I installed
them on my hand-built John Smith Universal organ.

Instead of the tissue paper I used the thin, colorful Mylar that is
used for wrapping gifts.  It comes in many colors so it can accent the
color scheme of any organ.  The kids are fascinated to watch them
fluttering and the adults like it too.

The strips are about 1/2-inch wide and about 1-1/2-inches long.  They
were attached with double-side sticky tape and do not affect the sound
in any way.

Another thing that captures much attention and interaction is a
Plexiglas back showing the inner workings of the organ.
