Sustainability can't be like some sort of a moral sacrifice or political dilemma or a philanthropical cause. It has to be a design challenge.
A part of my kind of design and inspiration ethos is that I carry around a leather notebook and I sketch in it, doodle in it, write notes in it, and I put pictures in it.
A chair is a very difficult object. A skyscraper is almost easier. That is why Chippendale is famous.
