French architects students from Collectif Timée (www.levoronoi.fr) have been appealed for the fair "Le Voyage à Nantes (www.levoyageanantes.fr ) to imagine and concretize one singular object, Le Voronoï, to provide a new perception of the surroundings. Answering this commission, they offer 1200 mirrors to the city. In a tree of a center of the city is hanging a bizarre egg. All at once, immense and immaterial, Voronoï is a phantom architecture. The closest you get the most invisible it becomes.This ellipsoid (6 meters high, and 4 meters large) is divided into 400 cells, according to Voronoi diagram (from free random space points, a mathematics formula creates cells from halfway lines around the points). Cells converges toward an unique point located at the volume center, to provide the effect of a huge kaleidoscope. When the street becomes busy, the whole structure trembles.To do so, they worked with a 3mm thick composite panels which are easy to transform, cut and fold.Geo coordinates: N47° 12.8686', W001° 33.2256'project info:Le Voronoï was designed and built by Collectif Timée, students at Nantes School of Architecture.client: Le Voyage à Nantesdesign and fabrication: Hélène Crusson Ripoche, Valérie Dabadie, Anna Le Regent, Adèle Leyris, Morgan Moreau, Mikaël Pors, Rosalie Robert, Pauline Trochuengineering consultant: Méca, Samuel Durandfaculty advisors: Michel Bertreux, Francis Miguet, Michel Dudonlocation: Nantes, Francestatus: on view until the end of Augustwebsite: www.levoronoi.fr
