Sony, in cooperation with the company E-Ink, has developed a special, tablet-like device, Sony Digital Paper, which represents digital paper on which you can write just like on classic A4 sheets of paper.
Digital paper
Um, how to explain that? First of all, we can ask ourselves, why would you even shine with a piece of paper? And the (legitimate) answer can be, why not? And it's true, why not. Well, it may also be for environmental reasons, since we use quite a lot of electronic material for lamps and batteries. So let's see what story Nendo, the paper lamp, tells.
Phree from Kickstarter - a smart pencil that turns the world into an infinitely large piece of paper
Phree is a pencil-like device that allows us to turn any physical surface into a virtual piece of paper. With it, you are no longer limited to the surface of the smartphone screen, where the smart pencil simultaneously "redraws" and saves your written ideas and sketches. At the same time, Phree brings us back to the times when we had more interaction with the world around us and makes sure that we don't forget to write by hand so quickly, you know, like this with a pen and not via a (virtual) keyboard.
