''Penultimate Curving Pavilion'' is a bisected teardrop shaped structure built of steel and two-way mirror glass, about 25 feet from point to curved end. It is an open, free-standing participatory structure for indoor and outdoor settings. Visitors can enter in two places where there are gaps in the exterior walls. The visitors looking at and through the structure, their imagery appears to change shape, because the glass is both transparent and reflective. The curved walls send back funhouse-style reflections, creating a new perspective on the built environment.
