Back in 2008 Nokia filed for patents covering a variety of new technologies that it is developing, one of which is for a "user interface, device and method for a physically flexible device".
The patents have only just been published and they include examples as to how this technology might work, including a bowl for dining and a can for drinking establishments.
Most importantly, the design will also be able to answer incoming calls, which basically means that it will be a mobile phone, but not as we know it.
At the moment it may be difficult to conceive of an interface which does not use physical or virtual buttons, but is instead responsive to the bending and waggling of the phone itself.
However, many manufacturers already use accelerometers and motion controls within their phones and with OLED technology being applicable to virtually any kind of material, a flexible mobile phone could well be with us within the next few years.
