Japanese electronics company Agic have released an advert for a pen that can draw working electric circuits onto paper. In the hypnotic video, created by Kandenko and called "Future with bright lights", a whole paper town is illuminated as the pen draws the outline of the buildings in current-conducting silver ink.
The video is created like a children's pop-up book, with a miniature street lights, houses, dog walkers and even a ferris wheel.
