An Art Lesson in Usability

I like Kimberly Kopp Krause's article
Your Web Site Is A Wonderland What Picasso's Art Taught Me About Persuasive Design, and recommend it to all who would like to understand good organization of a web site. Short quote:

Persuasiveness and desirability in web site design are in the details. They're in the point of view and in the delivery, and more than anything else, in the experience of interaction. They are that inner cosmic connection between the web site and site visitor.
