A company out of British Columbia has developed "Free Spirit Spheres," which are pods-houses suspended from trees. According to the company, these durable spheres can be used for all sorts of purposes: healing, meditation, photography, canopy research, leisure and game watching.
If they sound a little dangerous, don't worry, they're not. Spheres can be hung from the trees or any other solid objects like buildings or rock faces. A web of rope is connected to any solid surface, thereby replacing the foundation of a conventional building.
If nothing else, these Free Spirit Spheres redefine what it means to just be hanging out.
