Our 'head of human solutions' Nat is wearing a rather splendid jumper today, emblazoned with squirrels vert rampant, that makes her look a bit like a 1970s kids' TV presenter.

Hullo. Ben here. Michael Bierut, Pentagram partner, very kindly popped in to the office today to show some of his work and talk design. And about New York, the recession, architecture, Brick Lane, team structure, building regulations – all sorts. Amazing, inspiring, refreshing talk. Thanks Michael.
