«Light Display: Black-White-Grey» «‹Lichtspiel, schwarz-weiß-grau› was originally supposed to consist of six parts, but only the last part was filmed. The first five parts were supposed to show different forms of light in set combinations: from the self-lighting match, automobile headlights, reflections, moonlight, and colored projections with prisms and mirrors to the production of the ‹light prop.› The filmed part [...] consists of documentary photographs of a rotation light prop; and the large shots of the numerous discs, screens, mirrors, and ball-shaped structures join forces with the fades to produce an abstract play of light and shadow.»
