rfid
You will no-doubt appreciate who influenced the following movie (a Rube Goldberg machine – “The Way Things Go” by Peter Fischli & David Weiss and the Honda Cog commercial). Here BERG a design consultancy focused on finding opportunities that lie in networks and physical things, have produced some lovely work using RFID technology (RFID stand for radio-frequency identification).

A second application by BERG, based on RFID, is Sniff. Sniff is an interactive dog that “sniffs” objects that come close to his nose.
It reacts through sound and vibration while creating games through behaviors, melodies and emotional responses.
