English: The Biham-Middleton-Levine traffic model for a 144 x 89 lattice, with a traffic density of 38%. The model has self-organized to a periodic intermediate phase. The red cars and blue cars take turns to move; the red ones only move rightwards, and the blue ones move downwards. Every time, all the cars of the same colour try to move one step if there is no car in front of it. Please note that the video has been sped up such that only one in four frames is shown. The video was created from about five thousand PNG images generated by my own code written with MATLAB. Some relevant C++ code is located at User:Purpy Pupple/BML even though it was not used to generate this video.
