Doodle with electricity

This pen allows you to draw circuits onto paper that conduct electricity immediately. Watch as it lights up this paper town.

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.
