This permanent installation, designed in collaboration with Cristina Chiappini, is located at the entrance of the new Nice headquarters in Oderzo (Treviso), and is designed to react to the movement that by definition takes place in an atrium: the passage of people. The installation communicates with the atrium environment, drawing color flows that accompany the transit of visitors inside the space through the lighting of a three-dimensional semitransparent methacrylate grid. The motion detection mode becomes a characterizing element through the emission of thin beams of light, emitted by laser sensors, projected onto moving bodies in the form of red dots. The object also assumes the function of a memory archive, collecting and displaying as words floating between grid lines, the text messages that visitors can send freely.
