One of my team, Andrew Spooner (@andspo) has produced a wonderful series of three short films that interview leading lights from the broader design world about aspects of design that are important in the digital domain.
They are now all available on YouTube:
Tony Howard from the Transport Design Consultancy talks about helping people to navigate with wayfinding graphics: http://www.ubelly.com/2011/10/navigation-with-way-finding-graphics-a-conversation-with-tony-howard/
The Godfather of modern typography Erik Spiekermann talks about typography in the Digital Domain: http://www.ubelly.com/2011/10/typographic-design-in-the-digital-domain-a-conversation-with-erik-spiekermann/
And finally, record producer Gareth Jones talks all things sound: http://www.youtube.com/user/ubellyms#p/a/u/2/SG0Ou07IDhQ
The Sound one is my favourite but then I’m more musician than visual artist (although I use the word musician loosely).
