A short bluish vertical line moving left to right and back. And below a similar line in yellow. The visible effect is produced by combining the layers. Unlike as in an image processing program, the layers are connected in a cyclical manner. A little bit like an feedback loop. But implemented very simple, by not deleting the OpenGL buffer before drawing the next frame.
