First inspired to make the choreography of the wind visible when watching Indian fisherman pulling in their catch, Echelman states, "I was mesmerized by the form of their nets and the fact that they were so changeable and flexible. They became this three-dimensional form that had no weight."

The funnel-like space of the Museum's atrium suggested a cloud and "with recent news reports of North Korea's nuclear weapons testing, it became a nuclear mushroom cloud" rendered in the flag colors of each of the countries known to have detonated such weapons in chronological order: United States, Soviet Union (represented by Russia's flag), United Kingdom, France, People's Republic of China, India, Pakistan, and North Korea.

"I was surprised to discover that all four flags of countries from the earlier phase were composed of the same colors-red, white, and blue. The last four countries had more earthy colors- introducing green and orange and yellow. I began to wonder what visual affinities the first countries might share, and whether the last four countries' earthy colors might be related to the fact that they were formed more recently."

In this work Echelman is "interpreting the most violent weapon that we humans have ever created, using one of the oldest and most humble techniques of tying things together."
