Donaukanal is a concrete serpent that doubles as the city’s largest graffiti gallery and an urban jungle. We trace the emergence of a collective coalition of artists, plant whisperers, and drone pilots who engage in a long established space for international grafitti art. The activist planting of flora into interstitial spaces of concrete decay. Kanal Opal is the gemstone to be harvested out of aerosol ephemerality.
\The interventions at the confluence of urban art, rogue botany, and the techno-poetics of drone-enabled activism are part of an externalization process that puts the works of the one decade old Science Visualization Lab of the University of Applied Arts into new perspectives – the anarchy of public spaces.
Through autoethnographic drift and digital cartography, we document how these actors repurpose drones—originally designed for surveillance and warfare—as tools for lobbing seedbombs, Sedum and Sempervivum into inaccessible crevices of tagged retaining walls. The graffiti becomes a nutrient-rich substrate for vertical micro-gardens, which, in turn, destabilize the distinction between vandalism, gardening, and ecological protest.
We interrogate planting as a starting point for roots cracking concrete ideologies and drones buzzing like awkward pollinators over Vienna’s most chromatic corridor.
Martina R. Fröschl is a senior scientist and digital artist at the University of Applied Arts Vienna, where she leads the interdisciplinary Science Visualization Lab. With a background in media technology and media design, she earned her doctorate with the thesis Computer-Animated Scientific Visualizations of Tomographically Scanned Microscopic Organic Entities. Her work focuses on visualizing biological and ecological phenomena using advanced imaging techniques such as μCT, MRI, SEM, CT, MRI, SEM, and light microscopy.
A core element of her research is the creation of immersive installations that engage audiences emotionally and intellectually with urgent scientific topics—from biodiversity and systems ecology to human impact on the environment. Her animations and installations have been shown internationally, including at Ars Electronica Center (AT), Barbican Center (UK), SIGGRAPH Art Gallery (US), EPICenter (AU), NTU Gallery (SG) and ECC Venice (IT). Since 2020, she has also served as chairwoman of the PIXELvienna Society, supporting the digital art and animation community through curation and knowledge exchange.
