“Movement in Void” is an artistic investigation of the brain wave sensing technology, a reflection of the artist’s personal yoga, meditation practices, and a tribute to Nam June Paik’s famous artwork – TV Buddha. Through this artwork, Bryan Chung extends the popular notion of embodiment in interactive art, by abandoning all gestural interactions and resorting to pure mental, and meditative activities. The interactive installation engages the participants in constant awareness of their mental activities and which may echo the mindfulness practices in Buddhism. The work also accumulates the brain wave data of all visitors to generate the collective patterns that manifest through the mechanical movement of the reactive environment.
