Zachary Lieberman's work uses technology in a playful and enigmatic way to explore the nature of communication and the delicate boundary between the visible and the invisible. He creates performances, installations, and on-line works that investigate gestural input, augmentation of the body, and kinetic response. Working with collaborator Golan Levin, he created a series of installations - "Remark" and "Hidden Worlds" - which presented different interpretations of what the voice might look like if we could see our own speech. These were followed with "Messa Di Voce," a concert performance in which the speech, shouts and songs of two abstract vocalists were radically augmented in real-time by interactive visualization software. The collaborators have toured and exhibited their works widely, much to the delight of their audiences. Lieberman's installation / performance "Drawn", in which live painted forms appear to come to life, rising off the page and reacting to the world around them, recently won awards in the Ars Electronica and CYNETart competitions. Most recently, he presented "Opensourcery," collaboration with Spanish magician Mago Julian, in which open source software is combined with traditional close-magic to create a completely new realm of tricks.
