I've developed an allergy to the smugness of tech-minded TED talks, but this Chip Kidd speech about book design is quite good. If you're familiar with Kidd, you won't learn anything new, but his style of presentation is kind of adorable:
I do want to smack those annoying glasses of his face, although his delightful cartoon jacket almost makes up for it. The nice thing about reading a Kidd-designed book is that you can tell he actually reads the books he designs. And he's worked on so many great books through the years that a Kidd design is almost a seal of approval, a sign that the book is at least going to be an entertaining read.
