Have known about this for a while now and this seems like the most impressive mobile phone CONCEPT out there. It actually holds the Guiness world Record for the smallest phone ever made. perfect!

The Modu mobile phone and a variety of "jackets" to pick from. What you actually do is put the Modu in the jacket you need and it changes its functionality head-to-toe.

The so called jackets are shells that can alter every single aspect of the phone. From display size and available memory to battery power and software functionality.

Confused? Don't be! With Modo should you need good music listening experience, all you need to do is put the Boom Box jacket on. It provides stereo speakers, nice intuitive audio player interface and so on. If you are in for a game - just change to the game jacket and you get a powerful large screen gaming console in your hands.
