Tuan Andrew Nguyen wore a distinct cabbie cap the night we met at a café on the outskirts of Los Angeles in late February. The hat served as something of a thinking cap and although the peripatetic, down-to-earth Nguyen had only been in town for a few days, he revealed he was crafting something subversive in the City of Angels. Based in Ho Chi Minh City (HCMC), Nguyen was visiting LA to acquire a life-sized, osteological reproduction of a Javan rhinoceros skull, which he special-ordered from a skeletal replication company, Bone Clones, Inc., in Canoga Park.
