I am installing an interactive public project inviting participants to develop and envision public and civic amenities in a 3-dimensional model form. Participants will be provided with a medley of recycled materials and invited to create their ideal urban form on an oversized urban plot of streets, parcels and parks. This City-building installation allows participants to think of planning goals in physical terms, creating a platform for diverse voices. Playing and visualizing with the 3-dimensional forms engages children and adults of all ages. This model will be constantly changing as participants’ work builds upon the contributions of everyone. Participants will be able to understand the city as not only a place but as a comprehensive urban art form. The purpose of City-building is to use interactive arts to help people think about urban design and planning. It shows participants the challenges and excitement of building through a multidisciplinary process involving everyone.
