Our design concept for Forrest Place and the city of Perth presents a new form of urban tissue: part artwork, part architecture, part infrastructure and part media. This new 'sensitive tissue' is one that is engaged in a deeper understanding of natural forces, and Western Australia's aboriginal history, while simultaneously presenting a full range of technical expression emerging in the 21st Century. Currently, Perth is defined by a powerful set of opposing forces that pit growth and progress against the depletion of natural resources and rising sea levels, and places ancient cultures within contemporary civilization. In order for the city to reconcile these contradictions, a new ecological model that is based in self-generation, diversity and cradle-to-cradle ethics must be embraced. This does not mean a result that is anti-celebratory or anti-technological, rather quite the opposite.At a basic level, the proposal acts as a canopy and entry portal between the train station and Forrest Place, responding in specific ways to the various edges, views, flows, and environmental forces. At a deeper level, the design is a 'sensing tissue' ? one that collects energy during the day and emanates at night, energizing a media rich canopy for a nighttime interactive light artpiece.In terms of light, both natural and artificial, the artwork visualizes the juxtaposition between deeper 'aboriginal time' and modern time. The daytime experience is based in natural forces ? sun, wind, etc., while the night is based in technology and electric light. Overlapping layers of material make the project a kind of conceptual clock that displays changing patterns on the groundplane, representing daily and seasonal change. Solar energy is absorbed during the day by a plane of thin film solar photovoltaics. This stored energy is released at night producing electric light effects that range from simple color fields to more interactive registrations of the crowds and movement below. The concept reinforces Perth as the 'City of Lights', while presenting a self-generating energy capture system that serves as a model for future projects.Further functioning at other levels, the canopy doubles as an overhang for the 'stage' area and produces an ideal acoustical background 'band shell' for performances.
