The trouble with concept phone designs is that it makes even the sexiest real phone seem, well, a bit naff.

We mean, we love the Samsung Galaxy phones, but you have to admit that they seem a bit clunky compared to this fabulous concept design from Bon Seop Ku.

The design for Samsung was inspired by drawing with water on a table and is completely transparent. Even the battery is liquid (this is a concept, don't forget).

The device would have an AMOLED screen that you would be able to interact with simply by rubbing the water display with your fingers.

It's all a bit bonkers really, and we think that's why it's such a winner.
