[Tekst dostępny tylko w języku angielskim] Brainwave controlled analog instruments is an installation under development. The instruments are scavenged from oldschool hungarian teaching supplies, and rejuvenated through an arduino system. The instruments are controllable via brainwaves, and provide direct biofeedback for the users. Multiplayer mode is also possible. The system is available for further controlling other installations. Collaborations are welcome.
