This is the ADzero, a smartphone with a four-year old, organically grown bamboo unibody shell. It was designed by British student Kieron-Scott Woodhouse, a final-year product design student at Middlesex University. After his concept designs were spotted online, the 23 year old was approached to help design a real device.
The Android-powered phone is built with an eye on sustainability, but isn't scrimping on the technical: its packing a camera with a reportedly unique ring-flash that encircles the lens. It'll be released in China and the UK shortly, with a focus on getting it into the hands of design-focused consumers.
