jamie found a video on Warren Ellis's blog introducing a new way to visualize RFID fields. The film is by Timo Arnall and Jack Schulze. The subject is introduced in words on the BERG site (a design consultancy); the tech behind it is explored at Touch, a project that experiments with near-field communications. "This image is a photographic mapping of the readable volume of a radio field from an RFID reader. The black component in the image is an RFID reader... The camera has been fixed in its position and the reader photographed. Using a tag connected to an LED we paint in the edges of the readable volume with a long exposure and animate them to show the form."
