Now open at the Contemporary Art Museum St. Louis: “Relative Points” by Christine Corday and “Fiction Archive Project” by Guan Xiao. “Relative Points” explores the relative concept of center in a center-less universe, anchored by twelve 10,000-pound sculptures pointed in multiple directions. Guan’s immersive video installations encourage museum-goers to consider the relationship between the internet and reality. On view through April 21.
