'resonantware' from NEC - is a collection of
products said to be 'near-future ubiquitous
networking devices' visualized by designers.
amongst the futuristic designs is:

'tag' a malleable mobile phone.
the phones shape-memorizing material and multiple
pressure sensors allow the phone to change its
shape according to the mode, which the user can
alternate by changing the shape.

as far as we know the resonantware designs are
still not planned to be commercialized at this point.
