The phone you can take apart like Legos.

Like playing with LEGOs, a modular smartphone is a make-it-yourself device consisting of an endoskeleton base and modules that attach to create a custom phone. Don't care about having a camera? Swap it out for a larger battery. Want to update your display without getting an entirely new phone? You could do that, too.

Motorola has been collaborating on a mission to make these devices a reality with Dave Hakkens, creator of a similar initiative called Phoneblocks, since this past fall. Project Ara would result in less electronic waste with devices that last a lot longer. Leading 3D printer manufacturer 3D Systems also recently got involved in an effort to improve the phones' blocky aesthetics.
