Look closely and you’ll see your hidden home away from home. The Mirrorcube is a nearly-invisible treehouse that truly blends in with nature. Built with exterior walls made from reflective “spyglass,” the pre-fab structure reflects its surroundings to become almost undetectable. (An infrared film, invisible to humans but visible to birds is placed within the glass to stop kamikazes.) Designed by Scandinavian architects Bolle Tham & Martin Videgård, it’s got a wood and aluminum body, and comes complete with restroom, queen-size bed, and Goonies-esque rope bridge.
