Matching fractals are in square yellows. My line of thought is that the current fractal is only a small part of a much larger fractal represented by the largest of the 3 yellow squares. The way that the second yellow fractal has behaved thus far, it would appear to be creating exactly the kind of shape that would be necessary for the larger half completed fractal to complete. This gives us a pretty good indication of where the exit point for the largest of the fractals may be. Yellow arrows represent mostly sideways action, note that there are two paths for completion shown, one with a sharp drop and one without. Outside of fractals, this pattern also presents an opportunity for successive Inv HS patterns to form on the way up. Not sure if it'll be right but kinda cool how it all clicks together.
