Circular Spectral Analyzer 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 body of the sculpture.

Circular Spectral Analyzer is installed in the free103point9 Wave Farm
sculpture garden, and was created with generous support from NYSCA,
the Greenwall Foundation, free103point9, Experimental TV Center, and
Harvestworks.
