Drawing invisible wireless network fields

Experiments in Field Drawing by the people at Touch consists of a mounted pen connected to and controlled by an RFID reader (image above left). When the reader passes within the field of an RFID tag it is pulled towards a sheet of paper to make a mark, if no RFID field is detected no mark is made. By slowly passing line by line and a certain distance from an RFID tag the device can draw and visualise a cross-section of the tags field (image above right) which can then, by repeating the process a number of different distances from the tag, be built up to form a three dimensional drawing of the tags field. Below are two videos of the device in operation.
