After weeks and weeks of being rumored, Amazon's finally unveiled its first smartphone: the Fire. And, as expected, there are 3D-like features on board, with something the company's calling Dynamic Perspective. Thanks to this, Amazon's Fire will be able to do a number of neat things across different apps; for example, if you're looking at a picture, the view of it will change as you move the device around. To show off the effect, Amazon CEO Jeff Bezos used a 3D aerial view of the Empire State Building, which made the iconic building look as if it were popping out of the Fire phone's screen. The web browser can also take advantage of the Dynamic Perspective feature, allowing you to easily scroll through pages by simply tilting the phone.
