Viennese/Croatian design collective For Use/Numen make large web sculptures from packing tape. They use nothing but packing tape to create huge, self-supporting cocoons that visitors can climb inside and explore.
They’ve done several smaller works in the past, but their latest is the largest and coolest. At the last installation inside Odeon, a former stock exchange building in Vienna, the group used nearly 117,000 feet and 100 pounds of tape.
