Designer, implementor, user, writer A Fragment by Donald Knuth dl.acm.org Thus, I came to the conclusion that the designer of a new system must not only be the implementor and the first large-scale user; the designer should also write the first user manual. The separation of any of these four components would have hurt TeX significantly. If I had not participated fully in all these activities, literally hundreds of improvements would never have been made, because I would never have thought of them or perceived why they were important.

Drawing a frame The panels of tessellating hexagons have been laid to stabilize a path running through what remains of the nave of Rievaulx Abbey. They demonstrate the impact of drawing a frame around anything, even if that frame is nothing more than a plastic cell and the subject an area of grass. I like the way the path simply peters out to either side, with no sharply defined boundaries. John Pawson, A Visual Inventory White cloth
