Luzes relacionais by Ernesto Klar

“Luzes relacionais” (Relational Lights) is an interactive audio-visual installation that explores our relationship with the expressional-organic character of space. The installation uses light, sound, haze, and a custom-software system to create a morphing, three-dimensional light-space in which spectators actively participate, manipulating it with their presence and movements”(from Ernesto klar’s site) source: creative applications
