The Particle


Alex Posada is digital creator, researcher in the field of interactive and new media as well as producer and music creator. He moved to Barcelona in 2002, where he began to work on interactive design and electronic art projects and the development of physical interfaces for musical instruments. He developed various interactive installations, dance and sound installations. Shortly afterwards, he began to collaborate actively with local artists. He talked several workshops that focused on artistic creation with interactive technologies in many places about the possibilities of the interactive technologies for the arts. He currently directs and coordinates the Hangar interaction design and electronics laboratory (art production center visual artsin Barcelona), where he has carried out numerous projects in conjunction with other artists. At the same time developing independent projects such as multimedia producer and works in several groups such as Dorkbot Barcelona or Neuronoise.

“The Particle” is a kinetic sculpture that experiments with color, sound and movement. The continuous rotation, speed and light create visual POV, effects that define the spatial structure of the object. The translucent skin created from the moving light becomes visible, creating shape and volume, both inside and outside the object. How light emerges from the limited movement of each of the rings when there is a change in external conditions (visitors) or there is a random mutation. The sculpture forms and reacts by generating events that modulate the sound and space, constantly changing atmosphere and perception. Given that the regulatory mechanism of the entire design is based on the decision making haphazard manner, the new models are emerging from the previous naturally. The vibration of sound, color and visual patterns evolve into chaos or order according to evolutionary algorithms that govern it. The structures generated in this process can not be anticipated and evolve through continual iterations involving alterations to the programs and exploring the changes through interaction with the visitor and the software. The object, at the same time is a space for sensory and kinesthetic experience, a body with its own internal resonance.
