Zachary Lieberman is an artist with a simple goal: he wants you surprised. He creates artwork that uses technology in a playful andseamless way to explore the nature of communication and the delicate boundary between the visible and the invisible. He makes performances, installations, and on-line works that investigate gestural input, augmentation of the body, kinetic response and magic. Most recently, he helped create visuals for the facade of the new Ars Electronica Museum, wrote software for an augmented reality card trick, performed by Marco Tempest, and helped develop an open source eye tracker to help a paralyzed graffiti artist draw again. In addition to making artistic projects, Lieberman is co-creator of openFrameworks, an open source C++ toolkit for creative coding.
