This is the LG Flutter concept phone.This may very well be one of the most radically different designs seen in a concept phone.
The name comes from it’s resemblance to a butterfly. But it also resembles a boomerang or a weapon of some sort. So whether it is good or not depends on the eyes of the beholder.
It is certain however that it is not quite practical since I doubt its possible to use the full features of the phone single handed.
Anyway the phone is basically compact till you press the LG logo when it expands and reveals the full radically scrolling touchscreen. In the closed position the display just shows about enough information such as the clock, caller id etc.
This is the winning entry in the Design the Future” competition by LG and the winners reportedly received around 20000 US Dollars for their design.
