contact microphones

["Mark T. Khemmani" <mkhemma@xxxxxxxxxxxxxxxx>]

does anyone have any information of where i can get/make cheap contact
microphones? i'm having crazy dreams of putting contact mics all over my
house and begin the process of bathing my ears with sonic minutae. :)
and as we moving along, is there anyone out there that has done stuff like
this. i know there are plenty of people that have (and i bet many of you
duffi have as well), so gimme some links people. gimme the links!!!
coffee happily jerking me around,
