The space between things is important to me. The projections, that darkness between the words or the images is very important.

My videos rarely run longer than 20 minutes. They're made for private viewing in your home or specifically either that or for a gallery situation where you sit and look.

I loved music. Music was a big thing and so I started collecting records. I had a large collection of jazz records and that was something else I used to listen to. At night, there was a - what the heck was his name? There was a famous - Jazzbo Collins, I used to listen to at night, and some other guys.

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.

By being critical, you also develop your own style of what you like, what direction you want to move.

And yes, there are things I want to keep, that I like around me - especially when there's very little left. I just want to keep those little bits of reminders of my past. There are certain drawings from the '60s; certain little paintings from the '60s that I keep.

I consider drawings finished works of art, first of all. However, the ideas can be something that can be developed into something larger. I don't make so many drawings anymore since I'm working with language. I used to make more when I worked with sculptural things, especially the wire pieces.
