I first formulated the project aiming at presenting the device at "The Brain's Week", a national event around the brain. I add chance to benefit from administrative support and material means to design the first prototype, as well as creative inputs to help elaborate the pedagogical content. Incognu brought their recently acquired Emotiv Headset to make things smoother than using the lab EEG caps, La Ligue de l'Enseignement let us borrow his inflatable planetarium to build the system which saved us from building our own dome and projection system, and made the whole realisation much easier. Finally, Les Chemin Buissonniers handled the administrative work, financial prospection, production of the performance and communication, they build up contact and collaboration with artists and are now developping new perpectives for the Brainarium.
