I happen to love engineering. I love figuring things out in a spatial sense, that whole realm of working with mechanical parts, and the relationship of the parts, and things like ratios and the speeds of particular objects.
The impulse for me to want to make sculpture is because I want to make statements, really, on a purely emotional level. And it's also somewhat of a challenge to see how that can be done with materials and objects that really are not emotional, in and of themselves.
I guess I'm fascinated with motion because I find that whenever anything is moving, I have some feeling about it. It doesn't matter what kind of motion it is. A motion will always evoke some kind of reaction.
