One of the things that deeply interests me is how to make our cities more beuatiful, more delightful. The city should bring a smile. I don’t mean this in a trite, sentimental way. I believe this is an unquantifiable aspect of placemaking that is all too often forgotten. The mental health and psychology of urban life is often stressful, and we need every last bit to alleviate these dentriments. In addition, I have always been an advocate of protecting animal life in our urban areas, creating cities that are for all creatures, not just humans. The old Beijing tradition of pigeon whistles is one such elegant solution to these issues, creating a city that is aurally delightful, that provides a space and purpose for humans and pigeons, that gives a unique identity to a place. I hope this tradition does not die out.
