Four Way 4-Way, Summer, Section 3

Four Way 4-Way, Summer, is back in rotation!  I have reached the center of Section 3 and now I have to figure out what to do there!  So far, this section is pretty much the reverse of Section 2 and I will try to continue with that for the center.

Here is what the whole thing is looking like now.  Amazing how just changing the color sequence has such an effect!
