call for experimental music instruments

hi!
In these days I am designing a couple of experimental music instruments (EMIs), some of them arduino based, in order to use then in future workshops and exhibitions.

In my project I want to document the largest number of EMIs that I can and I know, and also, in some cases produce them when they are so simple that people without experience are able to do it in one hour. If some of you are involved in this kind of projects, please, send me an email with your circuits, descriptions and ideas.

The whole project (EMI) will be documented in a web site as creative commons license and of course, copyleft rights. It will be a wiki to store knowledge about this kind of devices.

If you are interested and you want to be involved, please send me an email to warholiano@yahoo.es and I will be able to give you for more info.
