"Wind Chime for Clara" was created by digital scenographer Anaitte Vaccaro for Fist Art Foundation for the inauguration of the Ritz Carlton Reserve in Dorado, Puerto Rico. The installation was inspired by pioneer aviatrix Clara Livingston and her contributions to civil aviation in Puerto Rico.

Using the theme of wind and projected onto kite-like butterfly objects suspended from tree tops, textures and animated leaves change speed and color, controlled by the surrounding wind and captured by sensor technology.

The sensor technology also controls the sounds of wind chimes enhancing the immersive experience of the installation with the goal of creating a truly authentic digital wind chime.

Video of the sculpture is captured using an infrared camera. This video stream is processed using background subtraction and adaptive thresholding algorithms creating a dynamic video mask. The mask is used to composite several video layers together, some mapped to the sculpture and some illuminating the surrounding elements. The system keeps the video mapped to the sculpture, despite changes in wind.   
 
An anemometer (wind speed indicator) is analyzed by the media playback system and used to control parameters of the video processing such as color, speed, and blending. Wind information is also used to trigger various audio clips creating a soundtrack of virtual wind chimes.
 
The entire system is implemented using Derivative TouchDesigner and Cycling ‘74 Max/MSP.
