In this piece, light is controlled by a physics simulator creating an astonishing effect.

A piezo electric sensor situated in the first bulb captures the force of the tap, generating a light particle that moves along the loop. All the shades of the energy are reflected in the trajectory of the light.

The system is powered by Unity 3D that simulates de forces that apply to the virtual corpuscle.

Comprised of 78 tungsten bulbs connect to a rack of 4 channel DMX dimmers, the installation is controlled by a physics simulator built with Unity3D. A piezo electric sensor situated in the first bulb captures the force of a tap, generating a light particle that moves along the loop. The initial impulse is regulated by the strength of the tap, creating a very natural interaction. When one hits hard light moves fast and can overcome the force of gravity, when one hits the bulb softly light falls slowly along the loop.

Light, as we usually see it, is an element that lacks mass, to treat it under the laws of gravity is somehow magical. The laws that describe the behaviour of light are hardly understandable because it neither behaves as body or as a wave. As Einstein wrote concerning the wave-particle duality: “We have two contradictory pictures of reality; separately neither of them fully explains the phenomena of light, but together they do”. In this project, we have built a computer simulator that reduces this extraordinary phenomenon to the simple classical mechanical laws.
