Check out the amazing Sketchbook of Susan Kare over at PLoS BLOGS. See the early iconic designs from the pioneer at Apple who is largely responsible for the leap from command line to intuitive Graphical User Interfaces. Steve Silberman has written a terrific article on how Ms. Kare, a Ph.D. in Fine Arts, came to Apple and changed the face of personal computing with her design insight. Dogcow, anyone? “The Sketchbook of Susan Kare, the Artist Who Gave Computing a Human Face.”
Kare has also self-published a book, Susan Kare Icons, a 160-page collection of her favorite icons done from 1983 to 2011 alongside explanatory notes and zoomed-in shots of the pixel level of detail.
