Yesterday we got to see the first Windows Phone smartphones from Nokia, the Nokia Lumia 800 and the Nokia Lumia 710, but not it would appear that Nokia has been showing off something much for interesting at Nokia World 2011, a Flexible smartphone prototype.

The guys from Cnet spotted the flexible smartphone prototype at Nokia World, and you can see it in action in the video below, and Nokia calls it the Nokia Kinetic Device.

It certainly looks very interesting from the video, the way the menus and on screen content can be changed by flexing the device. You can see lots more photos and find out more details over at Cnet.
