This is a monochromatic nightmare, an abstract film of highly experimental nature. Two individuals, two shadows. One black-and-white canvas, one story. Two silhouette figures, resembling both human forms and ghostly apparitions, continuously stretch, shrink, distort, and morph into bizarre graphic shapes against an empty backdrop. In over ten minutes of silence, they tear and struggle against each other, with no winner or loser. 　　 If anyone could master the manipulation of abstract geometric shapes to the extreme, it would be German director Oskar Fischinger. This black-and-white abstract animated short, produced in 1927, offered a refreshing and novel experience to audiences at the time. To achieve the dramatic visual effect of dynamic abstract geometric forms, Oskar built a wax-slicing machine himself and invented the "wax-slicing machine" technique.
