One of Grainger and Cross’s last experiments before&#13;
Grainger’s death in 1961 was an attempt to create a more&#13;
immediate and accurate form of Free Music through the&#13;
use of hand-drawn waveforms and light-sensitive&#13;
circuits. This experiment used photocells (light-dependent&#13;
resistors) rather than paper rolls and tone arms to translate&#13;
pitch and volume markings, painted on plastic sheet,&#13;
into sound. The original machine, never fully completed,&#13;
was eventually disassembled after Grainger’s death.&#13;
This reinterpretation also uses light-dependent resistors&#13;
but connects them to digital Teensy microcontrollers&#13;
loaded with the Mozzi software library. The addition of&#13;
the hand crank enables the looped ‘score’ to be played&#13;
forwards and backwards.&#13;
