The Umbra sculptures, like Twirling Umbra, are explorations of fluid motion, shadow and the use of not only negative space to bring the surroundings into the body of a sculpture, but also doing that by making the sculpture transparent. In some ways the holes hinder the ability of the sculpture to transmit it surroundings, but from other angles the case is the opposite.
I am very interested in having my sculptures meld with their surrounding. I have been exploring this through the use of negative space, primarily holes, in recent years. Transparency is a new way to ignite a sculpture by what surrounds it. More Umbra pieces are coming.
