Who is Banksy?

In Banksy's artwork he shows that art can be whatever you want to be.  My reaction to this is that he doesnt care about what people think, he does whatever he wants to do.  All his art is done illegally so it makes it that much better.

I think that he does graffiti art because thats how he chooses to express himself, and i think it looks really cool. 

I think by putting your art in a public place shows a side of confidence, and that you know your good if your doing that, or your afraid of critisizim so you do it so know one will no who did it.
