Mobile phones have come in all manner of different shapes and sizes over the years. Standard candy bars, clamshells, sliders, swivel designs - even odd origami-like multi-twisty phones. One thing all these different phone types have in common, though, is flatness. The fascia of the phone is always completely flat, largely because the screen itself has to be flat.

Somehow similar to the Snaked concept, the NEC Tag is a flexible phone concept that can be , for example, hung from a belt or wrapped around the user’s arm. Interesting is that the phone has shape-memorizing material and sensors that allows the phone to change its shape according to the mode.
