material use

I would have to say, after thinking about it a bit longer, that my biggest problem with Stelarc's third ear is that I don't understand why he had it implanted on his arm. I really need to know more about his purpose in order to be more accepting of it. As far as medical need vs. no need compared to the use of other materials by an artist that could also be needed for another purpose, I would have to say that it is not much different. I have actually been thinking alot about how wasteful we are as artists, especially since I've come to IUP. It is something that really concerns me.
