The text by Carl DiSalvo discusses opportunities and approaches which can be used to stimulate thought, provoke discussion and engage in the political. DiSalvo explores the political qualities of design by examining a series of projects including computational visualizations of networks of power and influence, therapy robots that shape sociability, and everyday objects embedded with microchips that enable users to circumvent surveillance. Each of the projects has political dimensions to it, using information and artefact to bring the selected topic into the public realm. The designer as critic and politician is a topic which is becoming increasingly more relevant in our complex and information saturated society. This book provides much food for thought.
