Susan Kare's sketchbook Nov 23 2011
Steve Silberman has a nice piece on Susan Kare, the woman who designed the original icons for the Macintosh, including a never-before-seen look at her initial sketches for some of them.
Inspired by the collaborative intelligence of her fellow software designers, Kare stayed on at Apple to craft the navigational elements for Mac's GUI. Because an application for designing icons on screen hadn't been coded yet, she went to the University Art supply store in Palo Alto and picked up a $2.50 sketchbook so she could begin playing around with forms and ideas. In the pages of this sketchbook, which hardly anyone but Kare has seen before now*, she created the casual prototypes of a new, radically user-friendly face of computing - each square of graph paper representing a pixel on the screen.
