It's a reflexion on how we interact with our surroundings. We influence nature just by existing. My intention is to highlight that fact.
The shape is inspired in different natural elements that give remembrance to concepts of movement, presence and non-presence like wind and fire or wind and leaves.
The mechanism consists of an arduino, a PIR motion sensor, an mp3 arduino shield, a mini audio amplifier and a servo motor. The PIR motion sensor reads infrared bodies and sends this information to the arduino. I programmed the arduino to start playing the track001 and move the servo motor every time the PIR senses something alive moving.
In this video you can see how the mechanism works.
Inside the wooden sphere there is a 3d printed plastic sphere that holds the weight to balance the structure and the electronic mechanism that makes it work.
Watch it work.
