Shadow Dance was a workshop proposing a creation of a tool that helps adjusting dynamically the lighting conditions for garden plants to perform optimal photosynthesis by luring humans to cast shadows in garden space by using sound.
A sketch of a device that was developed through an Interactivos? procedure in Nuvem residency, managed to measure the amount of light energy during the day and express the plants´ needs of shadow/light by an intuitively understandable and playful signal imitating a human voice that lured close by homo sapiens around closer to the plant and thus adjust lighting conditions by casting a shadow.
The project was proposed for Interactivos? by Mikko Lipiäinen and developed with collaborators Debora Leal, Raquel Rennó and Thiago Hersan by the kind help of artist Leslie Garcia, using improvised materials, a microcontroller with wireless connection shield, an affordable CO2 sensor and Pure data.
