Parhelia is a real-time audio-visual generative artwork where sample-based mechanical sounds are used to orchestrate a family of concentric architectonic forms in space. The scenes allude to the workings of an imaginary or pataphysical contraption whose component parts, or 'gears', interact with one another, triggering corresponding sounds as they do so. A variety of field recordings, including audio samples of mechanical and electromagnetic devices, form the basis of the sound design.

A Parhelion (plural Parhelia, from "beside the sun", also called a 'Mock Sun') is an atmospheric phenomenon that creates bright arcs and spots of light in the sky, often as a luminous ring or halo on either side of the sun. Parhelia are formed by plate shaped hexagonal ice crystals in high and cold cirrus clouds during very cold periods.
