Lighting Sensing Array
An array of light sensing photocells each tuned to a different tone. As light projects through opening (inversely as shadows move across) it will sequentially activate each photocell depending on the attributes of the opening (or shadow). An audio composition will be created by manipulation of light patterns and changes in light intensity. A circuit will be needed to produce and control each of the tones.
Opening located at 45 degree from Y (in line with sensors).
Opening located at 30 degree from Y.
Opening located at 60 degree from Y.
