This is interesting."These durable spheres can be hung from the trees as shown, making a treehouse. They could also be hung from any other solid objects or placed in cradles on the ground. There are four attachment points on the top of each sphere and another four anchor points on the bottom. Each of the attachment points is strong enough to carry the weight of the entire sphere and contents.The spheres are made of two laminations of wood strips over laminated wood frames. The outside surface is then finished and covered with a clear fiberglass. The result is a beautiful and very tough skin. The skin is waterproof and strong enough to take the impacts that come with life in a dynamic environment such as the forest."
