Signal Garden
An interactive sound garden where plants become instruments.
Overview
Signal Garden wires capacitance sensors to living plants; touching a leaf plays a tone. The garden learns simple harmonies as visitors play together.
Approach
- Microcontroller sensor network across 14 plants
- Generative pentatonic engine that biases toward consonance
- Kiosk installation with no visible technology
Outcome
Ran for six months in a museum atrium, logging over 30,000 interactions.
