Ranjit Bhatnagar created a stone sound sculpture that responds to the settling of its stones and the weather by playing sounds. This beautiful sculpture uses sensors for pressure, humidity, temperature, and barometric pressure to collect data and send it to a drone synthesizer, making the sculpture feel alive with sound.
Ranjit posted a bit of technical information on the project over on the forum.
This video is a walkthrough of the sculpture. You can hear the change in sounds the sculpture is generating while walking around it.
