This is a great, simple animated introduction to the design thinking of Paul Rand, enjoy....
This animation was created by http://www.imaginaryforces.com/archive/alphabetical/415
"For his posthumous induction into The One Club's Hall of Fame for 2007, Imaginary Forces created a short film, combining original animation with a videotaped interview of Rand himself, that encapsulated his unique and timeless contribution to the design community."
