Polish animator Piotr Dumala was among the filmmakers contributing to Academy Leader Variations, the short anthology that was the subject of a recent post. He also received a mention in the Screening Kafka post for his memorable animated portrait of Franz Kafka. Walls (1988) is another short film made just after Academy Leader Variations, and like all of Dumala’s films the images are created by scratching lines into painted plaster. The cross-hatching that results from this means the animated images are much closer to drawings than the vaguely similar pinscreen animations of Alexandre Alexeieff and Claire Parker. Walls is moody, inexplicable, and may be watched here.
