From the Berg blog, a description of their short film on RFID tags:
Following Nearness, the chain reaction film, is Immaterials: The ghost in the field, our next film with Timo Arnall at the Touch project. There are 4 billion RFID tags in the world. They may soon outnumber the people. Readers and tags are increasingly embedded in the things and environments in which we live. How do readers see tags? When we imagine RFID and their invisible radio fields, what should we see? Immaterials explains the experiments we have performed to see RFID as it sees itself.
