Questions of Discussion

• Something that has been in my mind for the past year is the idea of conceptualism, Bruce Nauman turned the camera on himself as did other artists but what is it exactly that is considered the "art"?  The finished product of the idea, just the idea, or the act of carrying out that idea, or is it just different for everyone who is aware of the idea?
• In retrospect to the article, the writer ends with the artist being in control of how the art is viewed, something that is not always controlled in other art forms.  They have the ability to alter the size, volume, speed etc. to their video.  Is this an unavoidable advantage that video artists have over all other artists?  And if so then does that make video artists the ultimate artists of portrayal?
