This book proposes, following Antonin Artaud, an investigation exploring the virtual body, neurology and the brain as fields of contestation, seeking a clearer understanding of Artaud's transformations that ultimately leads into examining the relevance Artaud may have for an adequate theory of the current media environment. The Artaud Effect is the only current full-length study of the relation of Artaud's work to dilemmas of digital art, media and society today. It is also singular in that it combines a far-reaching discussion of the theoretical implications and ramifications of the 'late' or 'final' Artaud, with a treatment of individual media works, sometimes directly inspired from Artaud's travails. Artaud has long been justly regarded as one of the seminal influences in mid- and late-20th century performance and theater: it is argued here that Artaud's insights are if anything more applicable to digital/post-digital society and the plethora of works that are made possible by it.
