Here's a couple of days' notice to plan to see Mexican-Canadian new media artist Rafael Lozano-Hemmer talk about his work at the Museum of Contemporary Art (MoCA) in Los Angeles this weekend. On Saturday, April 6, from 2-4 pm at the MoCA's Ahmanson Auditorium, he'll chat about the innovative forms he works in: relational architecture, technological theatre and performance art. Recently, Lozano-Hemmer's created "Vectorial Elevation," an interactive art project which transformed a square in Mexico City's with immense light projections controlled by online participants from around the globe (pictured). Hear him talk about his latest stunning work, "Body Movies."
