It is the most fascinating of all the sculptures, IMHO. We stand there watching an empty space! From time to time the hole disappears briefly. The whole thing apparently weights 3 tons (presumably the underwater equipment, not the hole itself)
"With sculpture the original material evokes a sense of weight and gravity, which expresses a sense of reality. This characteristic is the unique power of sculpture. With painting two-dimensionality is a given, yet we are able to share the illusion of time and space. With my piece I am trying to merge these characteristics, by using real materials in the real world, yet having the power of illusion that painting holds."
