Annie Vallotton might be the "best-selling" artist, but I think Susan Kare is far more relevant. Susan who? Here's a short bio:

Susan Kare received a B.A., summa cum laude, from Mount Holyoke College, and an M.A. and Ph.D. in fine arts from New York University. In 1989, she was a founding partner of Susan Kare LLP. She is a 2001 recipient of the Chrysler Design Award.

Still confused? I'm sure you interact with her works everyday, after all, she has designed icons and fonts for Apple, Microsoft, Intel, AT&T...the list goes on! Check out her portfolio, here.

But my favourite work of hers is a "portrait" of Steve Jobs, on a "canvas" of 32x32 pixels, see it here.
