Folding Unfolding: Collider is an interactive exhibition/installation, featuring 3D replications of basic seed crystals, such as borax, gypsum and quartz, from the collaborative team of lesbians Sarah Strauss and Lia Halloran. The pair was inspired by 500,000-year-old natural crystals discovered a decade ago in Mexico. On display through Jan. 12. Artisphere, 1101 Wilson Blvd. Arlington.
