In Zwerk Vegter used Fourier transforms (named after the French mathematician Joseph Fourier) – a technique in which a number of different frequencies can be compiled, thereby creating an image.
"Zwerk is an abstract film that depicts an illusionary world. The film is made with the purpose to create an opportunity to view something as it is. What remains is a visual experience. When making the film I let myself inspire by the words "at the edge of emptiness" and by my interest in the field between chaos and order." (Bart Vegter)
