Research output: Contribution to journalArticlepeer-review


This is a hybrid installation that creates an interface between people and cyanobacteria. The project integrates the photosynthetic activity of these microorganisms, the dynamics of environmental light and the bioelectrical activity of the participants. Using cell culture and computer vision, this work renders the photosynthetic activity of cyanobacteria in the form of an organic structure. It also produces dynamic geometries of solar energy by analysing environmental data. Simultaneously, this work transforms the activity of the nervous system of each participant into 'light' to stimulate the cells. As a result, visitors and cyanobacteria influence each other giving subsistence to a dynamic feedback system.
