This project explores the performative dimension of card game design in relation to theatrical research. Through a process of research-action, it aims at elaborating a state of the art game by organizing circles of players in order to test games coming from independent creation or those more general public. In this research, Benoît Renaudin (HEAD - Geneva) and Isis Fahmy (La Manufacture) seek to explore the link between design and theater when they are confronted in a common artistic process. They will create a performative card game by setting up a graphic and digital writing tool. This hybrid object, between design process and theatrical dramaturgy, will be the central element of a performance built by the two researchers.
