The book presents the research by the Action Space! Studio on the Evolutionary City. An ambitious project meant to create a new tool not only for urban planners, but also for people involved inside project management business and people outside that practice. A kind of simulator-educational tool. The journey of discovery began by understanding evolution starting with Darwin, his phenotypes, the realms of biology, sociology, and economics. Pumped by evolution's magic the studio quickly plunged into game theory. These two lines of research synthesized into a set of games modeled on diverse aspects of the city - from the tasks a building developer faces when dealing with land value to the more intangible aspects of a city (i.e. the driving forces of desires in social groups).

This volume of the "Delft School of Design" series focuses on the South African urban context, seeking to construct a contemporary critical dialogue of current spatial practices in relation to social, political and governance structures. The contributors-academics, urban historians, architects, policy makers-reflect on the possible paths forward. The book is divided into thematic sections: "Other Urbanisms," "Tradition, Culture and Education," "Urban Design, Civic Action and Agency in South Africa" and "Future Perspectives."

"Crossover" is the very first publication by the Delft School of Design (DSD), a laboratory for research and experimentation in architecture, urbanism and technologies of construction at the TU Delft. Its investigations cover a wide variety of subjects, from theoretical considerations and historical studies to urban and architectural practices and contemporary structural design. What they all have in common is the emerging condition of architectural and urban knowledge in both the academic context and professional practice. Since its inception in 2003, the DSD has developed a strategy or field of inquiry for mapping new means of approaching the complexity of the contemporary urban and architectural conditions. Traditional approaches are seen to be increasingly inadequate in the face of this complexity, and new technologies offer us the challenge and the potential to represent our world in unprecedented ways.
