Inaudible Frequency

May 24, ’12 6:45 PM

Inaudible frequency describes visually frequencies inaudible to the human ear. A fluid bath is mounted on top of a bass speaker which is connected to a frequency generator. The fluid in the bath assumes a waveform dependent on the frequency being played through the speaker. A spinning laser projects a circle of light onto the surface of the fluid; the result is photographed.

Record Trace Machine

May 24, ’12 6:30 PM

Record Trace Machine interprets an entire album or single as a visual waveform written in light. The result is photographed; the length of the exposure is determined by the length of time it takes to play the record.

Electro-luminescent String Waveform

May 24, ’12 4:15 PM

String Waveform explores waveform and additive colour mixing using electro-luminescent string. This red, green and blue illuminated string is mounted from apparatus that allows it to be rotated at a variable rate. The string assumes a waveform dependent on the speed of its rotation; this is photographed. Where the three strings overlap, the red, green and blue light combine to create white.

Cast Wavelength

May 24, ’12 3:36 PM

A constant inaudible frequency is played through a horizontally mounted speaker. Onto this speaker is placed a Petri dish filled with casting resin; the resin sets revealing a waveform on its surface – leaving a trace of the frequency.

Robot Trace

May 18, ’12 9:48 AM

Robot trace uses a line following robot to re-interpret work previously produced. The robot is designed to follow a black line underneath it. Instead of following a line, I have printed large format black and white prints of previous work which the robot negotiates. The robot has an array of red, green and blue LEDs on its back; these describe a trace of its path in a long exposure photograph, the LEDs mix to produce white light.
