Fabrication Methods for Polarized Light Collages
In this thesis, we discuss the best methods of fabricating polarized art collages, inspired by the artwork of Austine Wood-Comarow that creates brightly colored images from cellophane, a colorless birefringent material, placed in between two polarizers. Her artwork appears alive as the colors morph …
