I've been circuit bending old ball mouses for a while now.
I've plugged the output of the optical encoder inside the mouses to a speaker.
I tinker with the encoder disks.
I found an Epson mouse that has electric contacts encoders, making it sound quite different to the optical ones.
In November 2011 I was accepted to exhibit my installation in the "Workshop" modality.
Each artist is assigned two rooms. In one room we set up the workshop that will be used to generate the work in the other room during the course of Season Nº 8.

I recorded the sound made by the visitors in the Vernissage, here there are two extracts, a somehow quiet expresión and a noisy one.
