OLED panels are used in new art piece by Bill Viola

Bill Viola, an internationally acclaimed American artist, is presenting has latest art works - the "Transfigurations" series. One of the pieces (called Small-Saints) is using 6 OLED panels mounted on a shelf: 

The title of the series "Transfigurations" refers to the moment when a person or an object is transformed not by external means but from within. Viola says "the transformation of the Self, usually provoked by a profound inner revelation or an overwhelming sensation of clarity and fathomless emotion, overcomes the individual until literally a 'new light' dawns on him or her… Some of the most profound human experiences occur at times like these, arising at the outer limits of conscious awareness."
