Fluxgate was a snowball triggered sound sculpture commissioned by the Norlys Festivalen in Trømso Norway in 2000. A collaboration with the Norwegian composer Geir Jenssen (Biosphere) who provide sound samples. Sixteen stainless steel plates rigged with velocity sensitive midi sensors acted as targets for the audience to trigger various elements of an electro acoustic composition. The installation also featured a live data stream taken from a Fluxgate Magnetometer, this measured mean differences in the magnetosphere which modulated the quality of VLF recordings.
The installation was staged the during festival over three years the final exhibition of the work featured video samples triggered and projected onto the plates. Programming by Matthew Olden.
