This paper examines MyceliuMinds, an artistic project conceived by Matteo Domenichetti and curated by Milovan Farronato, as a case of digital artivism aimed at questioning the forms of sociality and power that structure the algorithmic ecosystem of social media platforms. Presented in 2022 at the Casa degli Artisti in Milan, the project unfolds through a video trilogy and a participatory performance - the Swinging Club - in which users exchange their Instagram profiles to experiment with new forms of cohabitation within digital space. The research is based on the analysis of the project’s visual and textual materials, as well as on a series of interviews conducted with the artist, the curator, and the participants involved in the performance. The investigation focused on reconstructing the networks of people, collaborations, and materials that made the project possible, and on examining how the work was received and discussed on Instagram, with particular attention to the effects it generated within specific digital communities. In dialogue with Shoshana Zuboff’s (2019) reflection on surveillance capitalism and Anna Tsing’s studies (2021) on mycelium and interdependence, MyceliuMinds is interpreted as a form of symbolic resistance and relational experimentation. The article aims to show how practices of digital artivism can open spaces for agency and collective reflection, suggesting new modes of coexistence and political imagination within the context of social media platforms.
