Light Frequency Fingertips instrument / performance

"Light Frequency Fingertips" is composed of four finger caps, each containing light sensitive phototransistors. The finger caps transform light frequencies into acoustic signals. Light, emitted by the displays of activated mobile phones, functions as the origin of the sounds. As each mobile phone's display generates a different light frequency, each results in an audio signal with a different pitch. In addition, other electronic devices, such as flashing bicycle lights, can be used to generate rhythmic tones.
