Two video art pieces reflect the artist's concern with the relationships between "electronic imaging, vision and hearing, language/text/music/sound, abstract cognition and perception under the investigation of the maker/observer and observers." "Avant coureur" utilizes the video screen to project and display highly contrasted images that cut quickly from frame-to-frame, thereby creating a room-size flicker/environmental box. The music throughout is by Kraftwerk. "Raster relief," a work in two parts, provides a conceptual literalization of the terms raster (video) and relief (sculptural and difference from the ongoing). The look of this work is dedicated to the "isms" of modern painting and sculpture and the respective pioneers of abstraction.
