A very futuristic and very original mobile phone was proposed by the South Korean designer Bon Seop Ku to Samsung. The apparatus is called AQUA and looks like it really is made of water.
The author of the concept found his inspiration not at all on the shore of a transparent lake or a fast river, but on a wet table, where he thoughtfully drew various figures with his finger. Thoughts formed into an idea, the figurines on the wet table turned into icons for the interface of an unusual phone, and the result was the conceptual Samsung AQUA, along with a graphical user interface (GUI) and a water-based display.
It is assumed that the user will be able to remove icons from the panel, simply rubbing them with his finger, as if erasing rain drops from the surface of the device, and, if necessary, re-display them on the touch screen. It is also assumed that the phone will run on a liquid battery, which will make it not only "long-lasting", but also environmentally friendly.
