An analogy of the relation between Principles and Language could be an abstract concept like “Love” (… a Principle) which could be expressed by a concrete symbol like ♥ or the combination of four characters “l-o-v-e” which give birth to the written form of the abstract concept “love”. I’m sure you could come up with an infinite number of other concrete ways to express the concept “love” including the sound of the word itself, photos or other metaphors.
That great little excerpt up above is one of the opening paragraphs to 31 Days of Windows Phone Metro Design, which we covered previously.
Since then two notable things have happened. The first is that Arturo Toledo, Sr. User Experience Designer at Microsoft and lead author of the series, has mentioned that the series will now be '31 Weeks...' instead of '31 Days...' so he can spend more time on each. Secondly, he has just posted the latest episode which goes over the process of designing an application from the top down - and he will be detailing each step in the coming weeks.
What I love about this series is that it's written simply enough for any developer to understand. And this latest post has even more detail than the last.
So devs, do yourselves a favor and go soak up all the Metro goodness.
