I would recommend that anyone interested in design and the creative process watch the American Masters TV biography/documentary on Charles & Ray Eames, running this week on PBS.
While the Eames Design Group is probably best known for their furniture design, they virtually pioneered the use of "multi-media" in communications, public relations, promotion, marketing, branding, etc.
I thought the show was fascinating. If you can't catch it on TV, you might be able to watch it here:
