Citizen Ex is an installation that uses a specially conceived algorithm to show us the path made by the information, both input and output, generated each time we access the Internet. It thus deals with a very relevant topic: the storage and traceability of the data used by individuals, companies, and technologies in different countries and jurisdictions. Citizen Ex shows the places where all this takes place and demonstrates how digital actions and virtual architectures redefine geography and so-called Algorithmic Citizenship.
