In February 2014, Switzerland voted in favor of a law limiting access to the country for immigrants, a decision I had to witness from the United States, unable to participate to the vote. The project, a compilation of self generated texts, news articles and data visualizations presenting the history of the country is an attempt at understanding the result of the vote. As the event of February 2014 highlighted a divide between the French and German speaking sides of the country, the book The Invisible Boundary plays with the idea of inclusion and exclusion, using red vellum to hide or reveal the French voice of the country, undermined by the German speaking majority in the country.
