The first film Rekveld composed according to methods he still uses to structure films. Featuring images created by recording the movements of a tiny light source with extremely long exposure times, so it draws traces on the photographic emulsion. The light is part of a simple mechanical system that exhibits chaotic behaviour.

In his film #43, Joost Rekveld observes what happens to a system that is destabilised by ‘creative' pixels, drawing inspiration from the set of ideas in biology and mathematics that arose during the development of cybernetics in the 1950s.
