Breath Vessels

Every breath is an exchange. What was inside you becomes environment; what was environment is integrated into your body, powering your cells. With every breath, the boundary between self and world dissolves — a practice in which we participate about twenty thousand times a day, almost never noticing.

In this interactive installation, a visitor exhales into a small shell-shaped device. As they breathe, a virtual 3D model grows in real time: the strength and speed of the breath at each moment determines the width of the vessel, so its silhouette becomes a direct record of that exhalation's rhythm. The resulting form is then 3D-printed in ceramic or PLA.

The cosmology of breath

Many languages reach for breath as their metaphor for the animating principle of life:

In Greek, pneuma (πνεῦμα) names both the air we breathe and the divine breath that animates the soul.
The Latin root spiritus persists in spirit and inspiration. In ancient Roman literature, the word afflātus referred to the divine breath said to inhabit poets at the moment of composition — literally a breath from the gods.
In Hebrew, ruach (רוּחַ) is breath, wind, and spirit at once — the same word that hovers over the waters in Genesis.
In Sanskrit, prāṇa (प्राण) is the vital life-force, moving through the body on the breath — the concept underlying the yogic practice of prāṇāyāma, the deliberate cultivation of breath.
In classical Chinese thought, qi (氣) is the animating energy of all living things, and breath is one of its manifestations.

Technical details

The custom software is not simply a visualization; it literally builds the 3D model in real time, exported as an STL using Karsten Schmidt's Toxiclibs library, alongside a captured image. Breath intensity is measured through an Arduino equipped with an accelerometer and Modern Device's Rev C Wind Sensor.
