In recent years, strange – ambiguous, dysfunctional, enigmatic, and complicated – objects have emerged in the world of design. These objects are based on an approach that has been called anti-design, radical, conceptual, or critical design – a speculative design that instead of offering solutions raises questions. Design that is not subject to the imperatives of the power structures of society, but is instead critical. Via a strategy of modifying objects away from their usual forms and utilitarian functions, this design evokes unusual uses and behaviours.
