Perspex cone and turntable.

In Green Line Cone and in Breathing Cone I found that by altering the way I passed light through perspex, either through the edge or through the sheet, the quality of light changed dramatically. In Green Line Cone the intensity of the thin green line feels like the high pitched note of a danger signal.
