Light projection, slide, dichroic filter, projectorJames Turrell designed Catso Violet in 1967, as part of the ‘Cross Corner Projections’ series. In this work, the artist created what appears to be a blue violet cube mounted in a corner of a specific space, free-floating, its source of light from a projection diagonally across the room. From a distance the shape has solidity but it is literally composed of nothing other than light. Advancing towards the work, the image eventually dissolves to the point where the viewer sees not the object, but the actual light on the wall. This piece objectifies and transforms our perceptions of light into a physically tangible material.
