This is a longer version of the video [ Ссылка ] without pauses, as requested by some viewers. It shows how sensitive dependence on initial conditions, known popularly as "butterfly effect", can be demonstrated by shining a laser on an array of cylindrical perfectly reflecting obstacles. From the start to the end of the simulation, the angle of the arriving laser beam changes by 0.000 005 157 degrees. To make the beam's path easier to follow, the color changes slightly at each reflection, and the intensity decreases slightly.
