Mar acts as an artistic "bowerbird," constantly gathering raw materials—from thrift-store finds, fabric scraps, and ethnographic art books to museum collection objects. By recombining these disparate elements, he constructs elaborate visual worlds that subvert traditional classifications. His work has been celebrated in major museum solo shows and public collections across the country, including the Perez Art Museum Miami, the Kemper Museum of Contemporary Art, and the High Museum in Atlanta.
