The interactive Space Time Transformation Footbridge is a conceptual design study for a new kind of pedestrian bridge that would be made of glass and steel. As people walk through the bridge, it senses their movements and responds by changing its shape from a pure cylinder to a multitude of varying shapes. As a result, the surrounding landscape is viewed by those crossing the bridge in an exciting fragmented way, which is based on the randomness of their movements. The glass, which covers the structure, is partially coated with a thin photovoltaic film that converts sun light into electricity. This electricity is stored and used to transform the shape of the structure, and to illuminate it at night.
