Because the concept and the interaction are interwoven, it is impossible to separate both items.

When you enter the darkened space, you can only hear the scrunching sound of an insect coming from three different directions. When your eyes are adjusted to the darkness, you see the sound is produced by three small, glowing objects. These life-like objects are hung just above the floor, it's long black wires running in the darkness.

The objects encourage the public to come closer to take a better look. When you are getting closer, the little glowing and buzzing object seems like a cocoon. But just as you are about to be convinced, the sound and the light disappear. Suddenly you are overwhelmed by the hovering sound of enormous wings. You have the chance to catch a glimpse of an immense butterfly, brilliantly flickering, enlightening its surrounding for a few seconds. The burst of light is produced by the thousands of capillary-like fibers. But as soon as the angel-like butterfly emerges, it disappears again.

Leaving the public in astonishment.

But as long as they remain close to the cocoon, nothing will happen again. An infra red motion detector in the cocoon notices when a visitor is getting closer than six feet. It lightens up the butterfly and turns off the light and sound of the cocoon, as long as the visitor stays too close to the cocoon. When the visitor moves away far enough, the soft sound and the light of the cocoon will start again. (S)He may approach the cocoon once more, lighten up the butterfly again, this time in another color.

Now the visitor will probably investigate curiously the other two cocoons. When (s)he approaches the butterfly, the sound and glow vanish, followed by the hovering butterfly, leaving in another direction. 

Site-specific covers a double meaning. Site originally means place where things can be found, This fits perfectly in the function of The Great Hall, where beside (and in) science man's search for knowledge is displayed. In the installation Butterfly, the experience of knowledge - or in the Zen way Satori - is visualized in light, by studying and observing nature. High Tech culture and the basics of man's experience of nature meet again in the Hall of Science.
