Immaterials: the RFID aura

This video and experiment called Immaterials from Timo Arnall has become very popular between the Internet of Things and proximity interaction communities in the last weeks. It tries to decribe the interactive properties of RFID by visualizing the activation area of RFID readers and antennas with long-exposure photographs.

The results are not only aesthetically impressive, but a very good learning material in order to understand how RFID fields work.
