Hartmut Esslinger, the founder of legendary frog design, just released his first book “A Fine Line – How Design Strategies Can Shape the Future of Business.” Throughout his 40-year career, Esslinger’s work has had a major influence on the modern consumer aesthetic with such revolutionary products as the Apple Macintosh computer, Sony’s Trinitron television, Lufthansa’s brand and fleet image, and Louis Vuitton’s brand aesthetic. In conversation with Guy Kawasaki, Esslinger discusses his perspectives on how “authentic human design” can connect strongly with both consumers and the bottom line.
