I've seen that before, quite a while ago. Really cool piece of tech.klasbo said:

But more on topic, I don't see the point in it. The controls look really limited an un-intuitive. I can't think of any kind of function any computer could do that would be improved by the use of a bending gesture. Sounds pretty silly to me.
Although paper-thin gadgets are interesting. I remember they used to keep going on about a mobile phone made of stuff like this, that was little more than a strip than curled up around your wrist. Also just generally the thinness of the circuitry would work well for our seemingly never-ending quest to make gadgets smaller and thinner. I guess one day we will have something as powerful as current high-end PCs that are small enough to fit in our pockets with ease. Come to think of it, we have probably done that several times over already. Take a look at how impressive smartphones are now compared to computers from just 10 years ago.
