eeefff is artistic cooperation / made-up institution / cybernetic political brigade / poetic computations / hacking unit / queer time. It is neither one of these, nor all together. Active from 2013. The group makes software-based projects, publications, networks, and platforms that critically explore digital labour, value extraction, and community formation. Methods include: public actions, online interventions, performative seminars, software, and hardware hacking, framing environments, and choreographing social situations. Co-organizers of Work Hard! Play Hard! in Minsk (2016-2020) and Decentric Circles Assembly in Warsaw (2024). The school of algorithmic solidarity was initiated by eeefff in 2022 to explore the relations between infrastructural time, algorithmic abstractions, and bodies.
