We don't tend to look closely at our streets. We feel their effects--the forlorn emptiness of a city megablock with monumental concrete lining its sides, the buzzy comfort of a narrow street with interesting shops and visual appeal--but we don't usually pick apart why they make us feel as they do. I never did, either, until this guy made me look at the world in an entirely new way. Walter Kulash was early to the game: The ideas he was pressing in the mid-1990's are much more common now. But then, he was a visionary, and well worth your attention.
