Phone producers show us every year some really superb concept phones and even if 99% of those phones never see the production line, they give us a small glimpse（一瞥）of what the phones will look like in the near future.
We’ve made a list of what we think are the coolest concept phones presented in 2010. But don’t ask us where you can get them and what the prices are.
1．LG Flutter Concept Smart-phone
The LG Flutter has a face like the iPhone.
The only difference is that the LG Flutter looks more like a fan or a killer’s tool which we see in sci-fi movies.
In spite of this, this design does seem fit for the future of mobile phones but looks a bit difficult to use.
2．Nokia 888 Communicator
The phone has an amazing design. You can fold it in many ways according to your needs. You can wear it as a bracelet（手镯）, roll it, bend it, and wear it as a clip on your clothes.
Nokia 888 Concept is mostly targeted at teenagers that are very active and take part in a lot of different activities.
3．Window Phone
It is a product to throw on the face of the shameless weather officials.
Whenever they predict sunny day be sure it would rain. So we have thought of gifting them this: “Window Phone” that makes accurate predictions and even changes its display（显示）according to the climate condition outdoors.
4．Nokia Morph
The Nokia Morph is created by Finnish company Nokia. The concept was the product of a joint study by the Nokia Research Center and the University of Cambridge’s Nanoscience Center.
The phone could be bent into numerous shapes，so it can be worn around the wrist（手腕）or held up to the face. The transparent（透明的）phone would allow it to be see-through yet functional. It has a self-cleaning surface that can absorb solar energy to recharge the phone battery（电池）.
5．Clover Phone
On looks it is just another ordinary phone type，but made in recycled material, which allow the device to be upgraded to meet the latest advancements in technology.
We guess the green aspects on the high-end tech will be a selling point for this phone.
