This assemblage is based on the talk I gave at the EASST010 conference in Trento, Italy, September 03, 2010. It is composed of several kinds of materials. The ground structure is formed by the slides I showed at that occasion. These slides are commented in three different ways. Firstly by excerpts from the talk, secondly by comments added now when this assemblage is put together, and finally quotes from “Design Things”, the book manuscript around which the talk circulated
