Endowing buildings with the capacity for movement and transformation, animated architecture represents the expansion of animation from cinematic and televisual space to real-space environments. A key example of animation in architecture is Oosterhuis.nl's proposal for a new World Trade Center. In line with similar work by fellow Dutch firm NOX, Oosterhuis.nl's Ground Zero embraces animation through references to mobility, liveliness and metamorphosis. It points to the prominence of animated form in contemporary design practice and the ubiquitous use of animation software in the process of architectural design. At the same time, Ground Zero reveals post-9/11 anxieties surrounding the soft and tender flesh of the object world. The author's analysis of Ground Zero's discursive production of life maps crucial changes in our spatial imagination and the politics of form.
