I have discs available that can be played on both Mr. Christmas Music
Boxes and Rhythm Clocks.  The discs are not plastic, but a sturdy
cardboard.  There are 11 sets (3 discs per set) available that I have
listed on my web page -- http://welcome.to/fenwickgifts

You can hear a Rhythm clock play Canon at my web site.  The sound is
not as clear as I would like, and it takes a while to load the entire
file, but it is my first attempt at adding sound on my page (I'm still
learning HTML, etc.).  If you are interested in ordering extra discs for
your music boxes please let me know at <kcylus@netscape.net>

Thanks,
Kirk Cylus
