New York artist Amy Chase Gulden has enlisted a scientific collaborator (Dr. Kristin Baldwin) and a microorganism (E. coli bacteria) to produce live, growing paints. Gulden traces outlines of natural forms – vines, trees, seaweed or neurons - with a paintbrush filled with invisible E. coli. After a night in culture, intriguing images appear on her canvas of agar. The outlines of her intention are apparent, yet the paint adds its own signature as it escapes her brushstrokes. This effect is closer to nature than traditional painting and produces images of unusual beauty, vigor and spontaneity.
