A bit tangential, but there's an interesting field of design called game design. In a company with clear responsibility division, game designer is not responsible for making things look pretty at all - the art director is. Instead, his focus is fully on core utility of game - fun. Inventing it, testing it, tweaking it, data-driving it. I think many designers in other fields would benefit greatly from taking a jab at a small game prototype. From history-defining classics like Pong and Breakout to iPhone, iPad - coincidence? Doubt it.
