The morph is that of a butterfly, which you can see in the blue light on the large screen in the apse. The rather haunting sound that echoes through the chapel is meant to correspond to cellular changes in the butterfly as it emerges from its cocoon.
The artist’s intention was to encourage stillness and silence, and only then can the participant watch the metamorphosis unhindered. I guess I was a little more entranced with myself when I experienced it than the artist intended. 😉 The installation is up through September 25 in the St. Cornelius Chapel on Governor’s Island.
