A video if line of white light is pprojected into a cluster of glass colour filters. Spittling white light into a spectrum of moving colour across the floor and onto the gallery walls. These colour filiter are the same as the ones inside the project the mix the red, green and bule light in equal amounts to achive white light (addtivie colour mixing used by electoinics to generate colour images). The white light is mixed inside the projector and then taken apart again by the filters. W witness a making and unmaking of an electroinic image.
