Put on the supplied 3D glasses and let Aurora Picture Show give your eyes a workout. Optical Illusions brings historic and contemporary experimental shorts together in Houston, exploring layered images, stereographs and anaglyph techniques through filmmakers including Jodie Mack, Ken Jacobs and Lillian Schwartz. Co-presented with Houston Cinema Arts Festival, this free afternoon screening is an unusual alternative to a multiplex trip. Seating is limited and available first come, first served.
