Could be something like this:
The short line gets rotated counterclockwise a few degrees each step, and one long line gets joined onto the existing line(s) for each step. At each step, the long line alternates between the "left" and "right" side of the short line. $$$$ The angles between the lines also get tighter with each step, but if they get much tighter it'll collapse into what looks like a single line; presumably not the intended solution.
