Situated in the heart of the Expo in the Piazza Italia, four 10 meter-high (33 ft.) shimmering tree-like sculptures will anchor the four corners of the central square. Conceived as gates each structure’s dynamic form spiral out of the ground and spread into two branches spanning 10 meters over the square. Crafted out of brushed aluminium and fitted with innovative LED technology, the Wings will animate the public space with a constant flow of pulsating patterns and imagery related to the theme of the Expo: health, energy, sustainability and technology. London-based media agency Innovision will provide the creative content for the display surfaces.
