A progression towards a horizon never reached, along sinuous lines and textured surfaces, with jerks, the fleeting passage of different patterns and detours along the side paths. You will notice that each movement ends roughly as it started.
first movement: rather sinuous lines ...
second movement: more textured surfaces ...
third movement: lines and surfaces deformed in 3D space ...
In the last movement, the symmetry between the beginning and the end is not obvious at first sight; however, after having more or less followed the course of a red line, the camera turns halfway so that - now along a blue line - we once again cross each of the objects encountered successively in the first half of the course, but seen from another angle and with some marginal changes in position or shape.
