Jono Williams, who designed and built The Skysphere in Linton, New Zealand, calls it 'not the ordinary treehouse'. It not only features a 360-degree window, but can be set up virtually anywhere. Its main characteristic is the futuristic- shape of the 33-foot tall tower and includes cool features such as: a fingerprint entry motorized door, high-speed internet, a rooftop stargazing platform as well as neon lighting at night. According to Jono Williams, who has a degree in computer graphic design, the building is entirely controlled via smartphone and powered solely by the sun. The whole building project cost him $50,000 and took him 3000 hours to complete. The process is documented on his blog. Nicely done, Jono.
