Biometrical Turntables

These modified turntables generate audio from pictures of the human iris. Light sensors mounted onto the pickups turn light modulations of the spinning image beneath into analogue audio waves.

The iris itself provides a rich pattern of individual strings and shapes. When spinning beneath the sensor, the occurring changes in brightness are converted directly into analogue waveforms. The signal is amplified by custom electronics and put out through stereo speakers.

The performer can generate audio by repositioning the pickups on the human iris. and modulating rotation speed and multiple amplification parameters.
