The Swiss magician began his performing career as a stage magician and manipulator, winning awards and establishing an international reputation. His interest in computer-generated imageryled him to incorporate video and digital technology in his work — and eventually to the development of a new form of contemporary illusion. The expansion of the Internet and social media provided more opportunities for digital illusions and ways of interacting with audiences and creating magically augmented realities. Tempest is a keen advocate of the open source community, working with artists, writers and technologists to create new experiences and research the practical uses of the technology of illusion. He is a Director’s Fellow at the MIT Media Lab.
