Internationally renowned contemporary artist, Bill Viola has over the years continued the study of the medium of video art.  The central focus of most of Viola's work has been universal human experiences including birth, death and the development of consciousness.  Like many video artists during the 70s and 80s Viola's interest in Zen Buddhism has influenced the feats in which he attempts in many of his work.  I enjoy a lot of Viola's work and appreciate their pursuits.  For although he does not push his body to the degree of some of his peers like Vito Acconci or Chris Burden, his involvement is still very far reaching.  Many of his videos involve water, which gives a temporal aesthetic that is visually activating. I can only imagine what witnessing one of his performances must be like.
