Seoul-based designer Bon-Seop Ku's wicked concept phone has a killer, if fictional, interface: The "Aqua GUI," comprised of water bubbles presumably manipulated by an electric current.

We should point out that while other blogs have picked this up and are insisting this phone was designed for Samsung, we believe freelancer Ku did it on his own purely as a concept.

In any case, it would be cool if you could pop the phone open and drink it during a dehydration emergency.
