What is art?

I sometimes wonder if computer created art is REALLY art. We have friends who have an amazingly talented ds who does some of his art on computer. There is no doubt that this young man is talented. Plus he can create without a computer. :) Someday I am sure you will all know who he is. BUT when I see something like this, it makes me wonder. I wonder if this person could do something like this on a canvas. I have my suspicions. Plus, I somehow think that there MUST be a trick to it. But I thought you would enjoy it. And maybe you won't think my posts are so boring.
