One week workshop at Le Signe - Centre national du graphisme in Chaumont with twenty other students from France and Ecole de condé. This workshop was talking about codex and its future in the digital age. We wondered how to build reader profiles in a new generation which is deploy new forms of reading. We created In-quarto, a platform that provides access to a rich literature, and adapted to everyone. There is a fun part in inviting the user to create and print his book "homemade".
