Saturn's hexagon change in season. These changes were observed by the Cassini spacecraft. One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere. Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery. The most common shape was six sided, but shapes with three to eight sides were also produced. The shapes form in an area of turbulent flow between the two different rotating fluid bodies with dissimilar speeds. A
Man with a Movie Camera modern Soviet Union they discover and present in the film. "Man with a Movie Camera" is famous for the range of cinematic techniques Vertov invented, deployed or developed, such as multiple exposure, fast motion, slow motion, freeze frames, match cuts, jump cuts, split screens, Dutch angles, extreme close-ups, tracking shots, reversed footage, stop motion animations and self-reflexive visuals (at one point it features a split-screen tracking shot; the sides have opposite Dutch angles). "Man with a Movie Camera" was largely dismissed upon its initial release; the work's quick-cut editing, self-reflexivity, and emphasis on form over content were all subjects of
