Having popularized stripped-down graphics and glitch effects, David OReilly opened up the aesthetic horizons of 3D animation with richly imagined lo-fi absurdism and a surprising soulfulness. Known for the influential shorts Please Say Something (2009), winner of top awards at the Berlin and Ottawa film festivals, and The External World (2010), he was Cartoon Network’s first-ever “guest director” on the fifth-season opener of Adventure Time, and created video games for Spike Jonze’s Oscar-nominated film Her. The animation star has since developed his own high-concept game, Mountain.
