Concept Development: This technology also reveals potential for a robust system that could be set up in an urban grove or protected forest as a semi-permanent installation; a Symphony of the Trees. The project moves from an expert moderated system, to a performative/interactive user based system, to an installation where a grove of trees is engaged over the length of a growing season. From a structured relationship to an improvisational relationship then to an open relationship each setting has its own unique potential to explore the empathic relationships that may lead to the ethical-obligation for living things.
