Created by Polytron Technologies and dubbed ‘Switchable Glass’, the phone uses liquid crystal molecules with a conductive OLED screen – which are aligned by electric currents to display images and text.
Despite the obvious hardware that’s currently visible through the phone, it’s still a fairly impressive-looking piece of kit – and apparently will be lighter and cheaper than the iPhone 5. Tempted? Keep a look out for the finished item appearing in (or blending into) shops near you.
