Using Silver Ink Circuit Pen To Create "Future With Bright Lights"

This pen by Tokyo-based startup AgIC can transmit electricity with its silver ink. You can see it in action in this inexplicably soothing video by a Japanese infrastructure company named Kandenko. A tiny 3D miniature paper town comes to life as the pen simultaneously conducts electricity as a person draws lines. The pen can be bought on Amazon for 1,296 yen (about 12$.)
