Tom put me on to this great film from Frog Design and unusually good interview (for Core77) with Jona Damon of Frog. I'll embed the film below, but do click through to the interview as Damon's thoughts on the few bits of Rams' 10 principles that may no longer be so relevant, make very interesting reading.
PS. Annoyingly I can no longer use my 'design thinking' tag for stuff like this as it has been usurped by a less obvious and more irritating meaning (for which I think 'designer thinking' would be a better term). So will think of a new tag.
