I didn't get to dConstruct, which was a shame, I was especially looking forward to Tom Armitage. Fortunately, the audio of his talk is available here. It's lovely, it made me think of this moment from Tinker, Tailor, Soldier, Spy:
"Taking the marble he slowly rolled it round his hard, powdery palm and Roach knew at once that he was very skilful at all sorts of things; that he was the kind of man who lived on terms with tools and objects generally."
