Phones with dual displays have been done, and Sony's foldable Tablet P brought similar functionality to tablets with mixed results. It looks like the Japanese electronics giant isn't done with such devices, however, as it's just been granted a patent for a gadget that can fold on multiple axes. The patent in question describes a device constructed of two rectangular casings that can be "rotated relatively in one of a first rotation direction and a second rotation direction orthogonal to each other." Translation: a sort of next-gen Jacob's ladder with hinges that open up on both sides of a right angle, which would allow you to set screens side by side or on top of one another. Want to know more?
