The brain opera evolves through collaboration with participants.

A complex system of interactive interfaces and "hyper-instruments" was designed for the Brain Opera.

Input > Interactive interfaces allow participants manipulate sounds and images using gesture, touch and voice at the Brain Opera¹s interactive installation sites (see image above.

Output < Participants¹ contributions are collected, then processed and re-distributed as sound and image material that is triggered by musicians playing the "hyper-instruments" at Brain Opera performances.

Feedback >< Interfaces were also designed which allow participants to contribute sounds and images and participate in Brain Opera performances over the Internet.
