In an environment of 37 degrees, our body temperature, visitors feel the warmth – energy – that nourishes us and all life within us as they walk through a visual installation of dense cancerous tissue. This energy enables the growth of cells and bacteria in our bodies and their exchange with each other. This exchange can be influenced by magnetic fields, which visitors can experience in an interactive simulation. The immersive spatial installation presented in focusTerra invites visitors to merge technology, research and imagination and follow the bacteria on their magnetic flow. Since 2013, Winterling has explored bioluminescent microorganisms in various artistic endeavors, including the striking installation “Planetary Loop of Gravitation” (2018). Building upon her extensive engagement with these life forms, she established the interdisciplinary network called “Planetary sensing: navigations below the surface.” This network brings together experts from fields such as philosophy, marine biology, microbiology, astrophysics, and social sciences, collaborating with residents of Oyster Bay, Jamaica. The collective investigates marine dinoflagellates inhabiting the region. These single-​cell organisms emit light when in motion or upon contact, holding significance not only in Jamaican cultural mythology but also providing valuable insights into marine conditions and pollution levels.
