Symbiotic organisms composed of fungi, algae (or cyanobacteria) and other microorganisms colonize the concrete of Petržalka. They are witnesses—they grow slowly, absorb substances from the air and thus record what has happened in Petržalka. They are painters—they glow with a handful of colors and textures on the gray, seemingly barren concrete. They are unassuming and quiet neighbors. They don't destroy the concrete; they simply like its nature. Anchored and resilient, they slow down to survive periods of drought and grow in times of high humidity. They also live off the air, feeding on everything that flies around and falls on them. They coexist inconspicuously with us, but they can teach us a thing or two about cooperation, memory and resilience to change. The exhibition by [Matej Gavula](https://www.instagram.com/gavulamatej) and Jonáš Gruska was a sequel to the (now sold-out) book of the same name, charting the lichens of the borough. New high-resolution macro photographs, an infinite video loop and a ready-made concrete planter harboring various lichen species were prepared for the exhibition, offering an intimate insight into their world. The book is available in Petržalka libraries and [online at archive.org](https://archive.org/details/petrzalske-lisajniky). **Location:** LOM space, Bratislava, Slovakia **Date:** `2024-06-21 → 2024-06-23` **Collaboration:** Matej Gavula **Special thanks:** Kateřina Skotalová and Lukáš Prokop (technical help) ![[petrzalske lisajniky_1.jpg]] ![[petrzalske lisajniky_2.jpg]]
