John Thackara, director of Doors of Perception, gives a provocative talk about the role of design in finding solutions to the ecological crisis. After inviting us to avoid terms such as "future" or "sustainable" as they maintain a certain distance to the problem we face, he shows a rich set of projects he participated in. He makes the important point that the resources to be put in place already exist and that they might not necessitates complex technological developments.

A designer and researcher at Oslo School of Architecture, Timo Arnall offers here his perspective about networked objects and ubiquitous computing. His presentation, and the intriguing design examples he takes, highlights two phenomena. On the one hand, he describes how sensors and RFIDs can enable to "make things visible" as the title of his presentation expresses. On the other hand, he shows the importance of going beyond screen-based interactions.
