Call for Proposals

Passionate individuals and non-profit organizations from the region of Rennes, Brittany, France invite you to participate in the first Breizh Entropy Congress. This inter-disciplinary event focuses on free (as in freedom) creations and culture.

Through a meeting fostering open-mindedness, exchange of ideas and learning, we hope to show solutions to technical, social and political problems, and celebrate free, reclaimed and creative art and technology.

We happily welcome entropy, as a means to break artificial boundaries between disciplines and find unexpected ways of doing things that promote liberalization, sharing and reclaiming of technologies that traditionnally belonged to the realm of corporations and well-funded academic labs.

NB! We are grateful for any kind of distribution of this CfP!

Breizh Entropy Congress is a zero-budget operation entirely run by volunteers and we therefore cannot help anyone with their food, travel and accommodation expenses. However, we might be able to arrange makeshift accommodation for participants in need, contact us for more information. Breizh Entropy Congress is not an academic conference.
