From the Franklin News (Oct 7, 2016, Abrahm Hurt):

During the planning and construction, Berg wanted to create a structure that conveyed the ideas of freedom and shelter.

“I want [viewers] to think and feel about the human condition,” he said. “I want them to ponder: ‘Why would somebody build a structure like this?’ There is sort of a weirdness to making things in the world that aren’t tied to function. So obviously, my motivation was to use aesthetics, to use form and to use the relationship of those two forms to convey a kind of unity and a kind of freedom—and also, at the same time, a kind of humanness.”
