The model is a simply rectangle boxes joint together on the tip of each other to quickly and simply make a long sequence of boxes, alternatively being a long tunnel. As you enter the tunnel at the beginning of the video, you see can instead of lights beaming the colour I have coloured panels to communicate by idea which works in the same way.
