"Behavior is our Medium", presentation by Robert Fabricant of Frog Design at the recent Interaction'09/IxDA conference 2009.

Robert Fabricant talks about Interaction Design as a practice beyond just computing technology. He gives examples of Interaction Design as far back as ancient history, all the way to a humanitarian project underway today. He shows that Interaction Design's primary medium is behavior, extending far past the high technology world into the realm of human behavior and relationships.
