I make videos which are works of art in themselves which have nothing to do with Hollywood movies or anything along those lines and I like videos because they deal with light and dark and time and change and they're just another kind of medium that I can get into and work with when I choose to other than, say, doing something on the wall or a window.

The only problems I sometimes have is if I ask for a piece for a group show, if I ask for a piece - I would like to put it into a show, sometimes the collectors get possessive about it and don't want to let something happen. Say you get full credit, you know. You give them your name, the catalog and it always enhances the value of the piece, you know, the more shows it is in, blah, blah, blah.

After I did the drawings of trees combining them with words, I started doing - I did that for a very short time. Then it kind of - that sort of evolved into just showing the branches of a tree coming down into the trunk and then going into the root system. So I showed both the branches and the roots of a tree, which were about equal. There is as much going on under the ground as is going on above the ground, which you can see.

I don't really use still photography very much anymore except to document my work.

You can never really predict how people are going to react, what they're going to think about, whether they care.

And style, by the way, is a very important thing. It is like your signature, your handwriting or it is something that you develop that is your way of presenting yourself and also your way of looking at what art - of how to make art.

But if I did read, say, [Maurice] Merleau-Ponty, for instance, it always seemed to me that the parts that I understood in what he was talking about - and I read him because - well, he wrote a book, well, the Phenomenology of Perception [New York: Humanities Press, 1962]. And it seemed to me that perception had a lot do with how we take in art.
