Forum (2020) is an installation and web application envisioning an infrastructure for future social networks inspired by the public/private aspects of fountains, ancient clepsydras (water clocks) and indoor bath culture. The installation contains a high concentration of salts, which form crystal structures around the clepsydra after a while. The installation is both a “discrete leisure” and public space that features a salt crystallization process, sculpturally marking a local space-time relation. Visitors are invited to interact with this process through a web application as they become part of a network of users connected through shared space and distributed time. Forum was produced for The Eternal Network exhibition at Transmediale in 2020 in cooperation with the Digital Solitude program of Akademie Schloss Solitude. It was exhibited at MGLC in Ljubljana as part of Iskra Delta, 34th Biennale of Graphic Arts.
