Numen/For Use — a Croatian-Austrian design studio — just created one of the coolest jungle gym installations we've seen in recent history. The installation is based on a production system of large geometric inflated objects. As the "String Prototype" deflates, the ropes loosen up, allowing compression of the installation. Upon inflation, the ropes tense to a perfect line, providing enough stength to carry the weight of a human being. The project is still in development over in the Viennese countryside, but we really hope this becomes the future of jungle gym fun.
