Overview

Butterfly Wall (2011) – San Francisco Arts Commission/San Francisco International Airport, Terminal 2, Children’s Play Area, San Francisco, CA. 12’L x 12’6”H x 1’W – Dichroic acrylic, stepper motors, custom electronics, glass & stainless steel casework. Butterfly Wall sets the conditions for the performance of an ever-evolving choreography set in motion by viewers who operate 10 hand-cranks to propel 20 mechanical butterflies up a cable to gently flutter back down again in a delightful random choreography dictated by the air resistance of their spinning dichroic wings.

Goals

The work serves as an interactive border between the children's play area and a busy passageway at the terminal. People can operate the butterflies on either side of the wall.

Process

I presented the design team with several concepts and Butterfly Wall is the one that resonated. The architecture team at Gensler suggested the precise location and the bend in the case. I designed everything. Control electronics were developed by SchmalzHaus in close consultation with myself. Rocket Science fabricated and installed the casework.
