In addition to its common usage in impact-resistant packaging, polystyrene (styrofoam) is employed as the creative material for Foam to Form, a project that touches upon the issues regarding the functions, forms, meanings and even aesthetics of polystyrene. A sculptural context is also introduced into this project in a way that plaster, a primary medium for sculpture, is used for casting the polystyrene. The casting process exactly embodies Luo‘s consistent creative spirit of exploring the invisible dimensions of materials.
