Consider him at work and excited by his project. His first practical step is retrospective. He has to turn back to an already existent set made up of tools and materials, to consider or reconsider what it contains and, finally and above all, to engage in a sort of dialogue with it and, before choosing between them, to index the possible answers which the whole set can offer to his problem.

John has caught us struggling to drive some 200 screws into a bench that is going to be delivered to a local school as part of a reuse interior design project. He teasingly preaches the merits of using mass-produced new screws instead. Maria responds in kind by holding up a salvaged screw, making a point about the merits of what they indeed do: reuse. Earlier that morning, Melissa, the other redesigner, had brought what she called a ' candy bag' of assorted salvaged screws and Maria and I are rummaging through it and some boxes of old screws looking for ones that will fit. Cramped under the bench, I envisage the jars of shiny new screws that the nearby DIY-store
