Mozilla developers crafted a video of Seabird, a concept of a phone with two pico projectors on the side of the handset, which can be used to project a large screen as well as a keyboard below. Don't get carried away though, there are no plans to commercialize it.
The big innovation is the use of dual pico projectors on the side of the handset, which can provide different functionality based on the phone's orientation: flat on a table they pump out the two halves of a QWERTY keyboard, up on a dock they offer the dual purpose of a large viewing screen above and a seamless projected keyboard below. Other features, like the pop-out wireless pointer / Bluetooth headset are slightly less realistic but no less charming. Now, before you get too excited, you should know that Mozilla has no plans to build this or any phone, they're just messing around with some fancy 3D software and the bright imagination of their community of users.
