Concrete Display

A couple of engineers have managed to create a concrete screen which has fibre optics embedded in to it. These fibre optics act as pixels displaying the tiny dots of light which come together to make the picture you can see on the wall. A light source is needed which can be an LCD projector for example. With this in the equation it could be used to display video as anything thrown to the back will be displayed on the front. Check out the video and be amazed
