I am indebted to Dr. Seuss for his story "Horton Hears a Who," which first gave me the idea as a child that worlds may exist though we can not perceive them.  What a concept!  Reality may not be what it seems. This cracked open my imagination.  As an artist, I wonder about the unseen, such as spaces between cells, the jostling of subatomic particles, the shape of the universe, and so on.  I am inspired by what lies at the threshold of perception.
