Null Objectis an intriguing publication exploring the project conceived by the collaborative arts practice London Fieldworks, founded by the artists Bruce Gilchrist and Jo Joelson, and the internationally acclaimed artist Gustav Metzger. The complex project plays with the idea of augmented mind by responding to the development of brain-machine interfaces, biometrics and the burgeoning role of databases across all conceivable sectors of society, and offers an alternative model for a creative, non-invasive interface between body, mind and machine for the production of art.
