Visitors to a recent festival of light art in Sydney, Australia, experienced a giant interactive sculpture. Japanese artist Masakazu Shirane (mah-sah-kah-zoo shee-rah-nee) and New Zealand artist Reuben (roo-bihn) Young created the installation, called Light Origami. Like origami (traditionally made of folded paper), the enormous structure is made up of geometric forms. There are more than 320 aluminum panels. Zippers connect the panels to one another.
