Circular Spectrum Analyzer* is part of the ongoing
Cross Current Resonance Transducer
collaboration with LoVid. It is a solar energy to sound and movement transducer. Two solar panels
directly power a shortwave radio and two motors. One of the motors continuously tunes the radio
across the 19MHz spectrum while the other slowly turns seven wooden discs. The shape and engraving
of the discs was determined by data collected from the seven Sunsmile devices in
Bonding Energy. The same data was used to engrave intricate patterns on the aluminum

Circular Spectrum Analyzer is installed in the free103point9 Wave Farm
sculpture garden, and was created with generous support from NYSCA, the Greenwall Foundation,

"Circular Spectral Analyzer," while Mr. Repetto (correctly) prefers "Circular Spectrum Analyzer".
Ms. Hinkis has withheld her opinion.
