Hexagon has no degrees of freedom but can seen as directed edges. Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations. The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them. The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between
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
