The Cinematic & Audio Visual Experimentation (CAVE) Festival is back and ready to blow your mind with works that push outside the traditional mold. In addition to film screenings by local and national artists, the multi-day event includes panel discussions and a cyanotype workshop. This year’s featured filmmakers are Nazli Dinçel, a Turkish-born artist who makes her work by hand in a film lab in Milwaukee, and Margaret Rorison, a filmmaker/curator based in Baltimore, who will lead the workshop. There will be an evening of pieces by University of Iowa MFA artists, plus a showcase of Minnesota artists. The festival culminates with a panel talk (11 a.m.) and a reception (1 p.m.) on Sunday at the Walker Art Center.
