Found a very interesting lecture - New Urbanism by an american architect and urban planner Andres Duany

Not sure how old it is, but I found it quite current and provokes a lot of questions about complying to codes and standards (and the conventional line of thought), which in turn is restricting the creation of successfull urban design projects!
