The rainbow by the Austrian architectural firm querkraft is a blend of engineering and dreams. Spanning 15 metres, the lightweight metal structure stretches across the ground and exemplifies what its creators have called “poetic pragmatism.” As a complement to the structure, performance artist Willi Dorner and photographer Lisa Rastl created a series of images in which people interact with the work. The human bodies become an extension of the structure and inspire visitors to engage directly with the rainbow themselves. Read more about querkraft: www.querkraft.at
