This book frequently uses “we” - referring both to all of us as citizens of Earth, and to Mouna Andraos and Melissa Mongiat, along with their team at Daily tous les jours, as they explore new ways of living together. It is an invitation into their journal. For over fifteen years, they have created interactive public art around the world, using music, movement, and storytelling to spark connection, joy, and care among strangers. Through this book, they share an evolving practice that blends technology, design, and performance to ask deeper questions and imagine new forms of collective life - beyond the urban masterplan, toward infrastructure for the human spirit.
